In a large gallon size zip-top bag or bowl, combine the chicken, brown sugar, paprika, cayenne, garlic powder, thyme, lemon zest + juice, salt and pepper and 2 tablespoons olive oil. Toss to evenly combine.: When you mix these ingredients, you should smell the citrus and smoke from the paprika almost immediately; that aroma tells you the seasoning is active. Make sure every piece of chicken is thoroughly coated, pressing the bag to distribute the marinade. This step matters because it builds surface flavor that chars nicely on the grill, creating a deep crust that seals juices inside. A common mistake is undercoating the chicken , which results in bland spots, so take an extra moment to massage the mixture into the meat. If your chicken pieces are uneven in thickness, pound them slightly to ensure even cooking and avoid dry centers.
Place the asparagus in a large baking dish and toss with 1 tablespoon olive oil, salt + pepper.: Once the asparagus is dressed, you should see a sheen of oil and hear a faint rustle as you toss the stalks, signaling they are lightly coated. This oil and salt are essential because they encourage quick charring while protecting the fibers from drying out. Properly oiled asparagus will develop attractive grill marks and an intensified vegetal sweetness. Don’t overload the pan; overcrowding prevents proper sear and leads to steaming rather than charring. If you skip the oil, the stalks can stick and lose their glossy finish.
In a blender or food processor, combine the sunflower seeds, basil, spring greens, garlic, 1/2 cup olive oil, pinch of crushed red pepper and salt. Pulse until combined and the sauce looks like pesto. Taste and add more salt if desired.: As the mixture whirls, watch it transform into a bright green paste, and breathe in the fresh herby scent that signals freshness. The toasted sunflower seeds should give tiny flecks and a nutty aroma, helping the pesto gain structure without being greasy. The olive oil binds everything into a silky emulsion that will coat the pasta; if it seems too thick, add a splash more oil or a little water. One pitfall is over-processing into a glue like paste, which can feel heavy; pulse gently to keep some texture and retain airiness. Stop and taste, adjusting salt so the pesto reads lively rather than flat.
Bring a large pot of salted water to a boil.: This water should smell faintly of the sea once salted properly, which ensures the pasta itself is seasoned from within. Use plenty of water so the pasta can move freely and cook evenly. Rapid bubbling will signal it is ready; drop the pasta in with a gentle flick to avoid sticking. A frequent error is under-salting the water, which yields a bland final dish even when the sauce is flavorful, so be bold with salt here. Watch the pot so it does not boil over when you add the pasta.
Heat a large skillet, grill or grill pan to medium high heat. Once hot, add the chicken and grill until char marks appear and the chicken is cooked through, about 5-8 minutes per side. Cooking times will vary depending on the size of your chicken. Remove the chicken from the grill and tent with foil.: You want a pronounced sizzle when the chicken hits the surface, a sound that foreshadows good browning. Look for deep, even char marks and juices that run clear; that’s your sign of doneness. Resting under foil lets the juices redistribute, keeping the meat moist. Avoid moving the chicken too often, which prevents proper crust formation. If you rush and cut immediately, the juices will spill onto the cutting board and the meat will dry out.
Add the asparagus to the grill and grill until charred, about 5 -8 minutes. Remove and keep warm.: As the asparagus chars, you’ll notice a sweet vegetal scent and an audible sizzle that becomes more gentle as moisture leaves the stalks. Proper charring adds smoky complexity and slightly sweetens the vegetable. Keep an eye so they become blistered but not blackened to the point of bitterness. A common mistake is leaving them too long which makes them limp and dull in flavor. Transfer to a warm plate so they stay bright while you finish the pasta.
Boil the pasta according to package directions until al dente. Drain and add pasta right back to the hot pot. Add the sunflower seed pesto, 1/3 cup of coconut milk or heavy cream and half of the goat cheese. Toss well to combine. Cut the asparagus into thirds and the chicken into bite size pieces. Add to the hot pasta and toss gently to combine.: The pasta should still have a slight chew, not soft or mushy, and the pot should carry the steam of warmth when you fold in the pesto. The aroma will shift toward herbaceous and creamy notes as the pesto and cream meld with the hot pasta. Tossing while hot helps the sauce coat each strand, with the goat cheese melting into pockets of tang. A key failure point is adding cold ingredients that shock the pasta, so ensure the pesto and any additions are room temperature or warmer. If the sauce looks too thick, reserve some pasta water to loosen it gently.
Serve pasta hot with the remaining goat cheese. EAT!: At the table, the first serving should show glossy, well coated pasta with specks of charred asparagus and shredded, bright chicken . The remaining crumbled goat cheese on top will add creamy bursts and a pleasing tang as it softens. Serve immediately for best texture contrast. Avoid letting the pasta sit too long, because the sauce can congeal and the dish loses its fresh quality. If you must hold it briefly, warm gently with a splash of reserved pasta water and stir to re-emulsify.
