Season salmon generously with salt and pepper. Heat 1 Tbsp oil in a large non-stick skillet over medium-high heat. Once oil is hot add salmon, top-side down and cook until golden and crisp on the first side (4 minutes) then flip salmon and continue cooking another 4 minutes or until cooked through, depending on thickness of salmon. Transfer to a plate and cool to room temperature then flake salmon with forks into bite-sized pieces.: The moment you season the salmon you should smell the faint briny sweetness of the fish combined with the peppery aroma, which will help build that savory crust when it hits the pan. Letting it sit for a few minutes at room temperature helps the seasoning adhere and promotes even cooking. A common mistake is overcrowding the pan later, which causes steaming not searing, so keep the filet alone or use a large skillet.
Arrange romaine lettuce on a large platter or large shallow bowl.: When the oil shimmers and moves fluidly across the pan, that is the cue that the surface is properly heated. You may hear a soft sizzle as moisture evaporates from the pan surface which ensures an optimal sear. If the oil smokes heavily, the pan is too hot and will burn the exterior before the interior cooks, so lower the heat slightly.
Arrange remaining salad ingredients in rows over the romaine lettuce; cooked corn kernels, sliced onion, quartered eggs, sliced avocado, and halved cherry tomatoes.: As the salmon hits the skillet you will hear a steady sizzle and see the edges begin to set and turn opaque, then develop a deep golden color. Resist the urge to move the fish, leaving it undisturbed promotes a beautiful crust. A common error is flipping too early which rips the surface and prevents proper browning.
Combine dressing ingredients in a measuring cup and stir to combine. Drizzle evenly over the salad just before serving.: When you flip the salmon the second side will sizzle and begin to firm up; watch the flesh near the center for a gentle color shift indicating doneness. Thicker filets may need extra time; use a fork to check that flakes separate easily. Overcooking dries the fish, so pull it off the heat just shy of done and let residual heat finish it.
Transfer to a plate and cool to room temperature then flake salmon with forks into bite-sized pieces: As the salmon rests you should notice steam subsiding and the juices settle, making it easier to flake neatly. Use two forks to break it into chunky, bite-sized pieces that keep some texture, not a paste. Rushing this step while it is too hot can make the fish fall apart into small fragments, so give it a short rest.
Arrange romaine lettuce on a large platter or large shallow bowl: When you lay out the chopped romaine lettuce , aim for a generous even layer that creates a canvas for the other toppings. The lettuce should be crisp and cold, providing contrast to the warm salmon . If the leaves are limp, the salad will feel flat, so always spin them dry thoroughly after washing.
Arrange remaining salad ingredients in rows over the romaine lettuce; cooked corn kernels, sliced onion, quartered eggs, sliced avocado, and halved cherry tomatoes: Placing the toppings in neat rows makes an attractive presentation and helps guests assemble their own plates with balanced bites. You will see color contrasts and textures come together visually. Take care with the avocado slices so they remain intact; arrange them last if you worry about browning.
Combine dressing ingredients in a measuring cup and stir to combine: As you whisk lime juice , extra virgin olive oil , minced garlic , chopped cilantro , chopped dill , salt and pepper, notice the fragrance shift as citrus and herbs mingle with the oil. A brief whisk emulsifies the dressing into a cohesive sauce. If you skip whisking you might end up with separated dressing that does not cling to ingredients evenly.
Drizzle evenly over the salad just before serving: The moment you pour the dressing across the salad, watch how the leaves glisten and the colors brighten, signaling a finished plate ready to eat. Drizzle lightly and then offer extra at the table so you do not oversaturate the greens. A mistake is dressing too early, leading to limp lettuce, so always dress right before serving to keep texture vibrant.
