Place all of the pulled chicken ingredients into the insert of your slow cooker. Mix to combine flavors, then put on high for 3 hours.: As the pot warms you will notice spices and broth starting to steam, releasing an aromatic wave of cumin, paprika, and lime. This low hum of heat is important because it allows the flavors to marry gently without toughening the chicken . Stirring at the start ensures the diced onion and bell pepper are evenly distributed and will soften at the same rate, creating an even texture in the finished meat. A common mistake is adding too little liquid, which can leave the meat dry, so ensure the broth and tomatoes create a shallow sauce. Keep the cooker lid snug to trap steam, you want a moist environment so the chicken becomes tender enough to shred effortlessly.
While it’s cooking, prepare the mango salsa: In a bowl toss together all ingredients and set aside in the refrigerator until ready to use.: In a bowl toss together all ingredients and set aside in the refrigerator until ready to use. : When you chop the mangos , red onion, and cilantro, you will see a bright palette of color and smell a sweet, citrusy perfume from the lime. Tossing the salsa and chilling it briefly allows the lime to slightly macerate the onion, softening its bite while keeping the fruit firm and juicy. Texture is key here, so aim for small, even dice so each spoonful has a balance of components. A frequent error is to make the salsa too far in advance, which can make the mango release excess juice and water down the mix. Keep it chilled and covered until assembly for the best crunch and brightness.
When the chicken is done, shred with two forks and mix into the sauce. Let sit for 10 minutes, covered.: As you shred, you should hear the soft tearing of fibers and see the meat flake into ribbons, absorbing the spiced liquid. The aroma will intensify, with warm spice notes playing against lime and tomato. Allowing the shredded chicken to rest in the sauce for 10 minutes is crucial because it gives the meat a chance to reabsorb juices, which keeps it succulent when scooped into the lettuce . One pitfall is shredding while the meat is too hot to handle properly, which can lead to uneven texture; let it cool just enough to shred comfortably. If the mixture seems wet after resting, use a slotted spoon at assembly to avoid soggy wraps.
Assemble lettuce wraps, top with mango salsa and other desired toppings, like avocado and tomato, and serve.: At this final stage the contrast of temperatures and textures is most apparent, the cool, crisp lettuce against warm, seasoned chicken and bright, cold salsa. Arrange the lettuce leaves on a platter, spoon the shredded meat into the center, then crown with mango salsa and slices of avocado . The presentation matters, because a tidy wrap invites people to dig in, so avoid overfilling each leaf, which can cause tearing and a messy bite. A common mistake is assembling too early and letting the leaves sit, they will soften; assemble just before serving for optimal crunch.
