Ingredients
  

For the Fiesta Lime Chicken

  • 1 pound chicken breasts boneless, skinless, pounded to 1/2-inch thickness
  • 2 tbsp olive oil
  • 2 tbsp lime juice freshly squeezed (about 1 lime)
  • 1 lime zest from 1 lime
  • 1 tsp chili powder
  • 1 tsp brown sugar
  • 3/4 tsp salt
  • 1/2 tsp ground cumin
  • 1/2 tsp smoked paprika
  • 1/2 tsp onion powder
  • 1/2 tsp garlic powder
  • 1/4 tsp chipotle chili powder optional, for more heat
  • 1/4 tsp pepper freshly ground black pepper

For the Avocado Salsa

  • 2 medium avocados ripe but still a little firm, chopped
  • 1 cup cherry tomatoes quartered OR 2 Roma tomatoes, seeded, chopped
  • Fresh corn from 1 ear sweet corn
  • 1/3 cup red onion finely chopped
  • 1/2 red bell pepper chopped
  • 1 jalapeno pepper diced (adjust amount based on heat preference)
  • 2 tbsp cilantro finely chopped
  • 1 clove garlic minced OR ¼ tsp garlic powder
  • 2 tbsp lime juice
  • 1/4 tsp ground cumin
  • 1/4 tsp salt
  • 1/8 tsp pepper or more to taste

Instructions
 

  • Step 1: Prepare and Marinate Chicken: Pound chicken breasts to about 1/2-inch thickness. In a small bowl, whisk together olive oil, lime juice, lime zest, chili powder, brown sugar, salt, cumin, smoked paprika, onion powder, garlic powder, chipotle chili powder (if using), and pepper. Rub this mixture generously over both sides of the chicken. Marinate at room temperature for at least 30 minutes, or in the fridge for up to 8 hours (let sit at room temp for 15-30 min before cooking if refrigerated).
  • Step 2: Prepare and Chill Salsa Base: While the chicken is marinating, in a large bowl, toss together the cherry or Roma tomatoes, corn, red onion, red bell pepper, diced jalapeno, cilantro, minced garlic (or powder), lime juice, cumin, salt, and pepper. Cover tightly and chill in the fridge for at least 30 minutes to meld flavors. (Can be made up to 24 hours ahead, adding avocado later).
  • Step 3: Cook Chicken: Cook marinated chicken using either the stovetop or grilling method until cooked through (internal temperature reaches 165°F / 74°C).
  • Step 4: Finish Salsa: When ready to serve, gently fold the chopped avocados into the chilled salsa. Taste and adjust seasoning with more salt, pepper, or lime juice as needed.
  • Step 5: Rest and Slice Chicken: Remove the cooked chicken from the heat and let it rest on a cutting board for 5 minutes before slicing. This is crucial for juicy chicken.
  • Step 6: Serve: Plate the sliced Fiesta Lime Chicken and generously top with the fresh Avocado Salsa. Serve immediately.

Notes

Substitutions & Additions: Substitute chicken with shrimp, firm white fish, or pork tenderloin, adjusting cooking times. Add black beans, corn, or diced cucumber to the salsa. Serve over rice or quinoa for a bowl meal. Adjust spice level by controlling jalapeno seeds/membrane and chipotle powder. Experiment with orange juice in the rub.
Tips for Success: Pounding chicken ensures even cooking and tenderness. Resting chicken after cooking keeps it moist. Chilling the salsa base allows flavors to meld; add avocado just before serving. Always taste and adjust salsa seasoning. Choose avocados that yield slightly to gentle pressure.
Storage: Store cooked chicken and salsa separately in airtight containers in the refrigerator. Chicken is good for 3-4 days. Salsa is best within 1-2 days as avocado may brown, though still edible.
