Spicy Avocado Chicken

1 teaspoon salt

¼ teaspoon ground black pepper

¼ teaspoon ground cayenne pepper

4 skinless, boneless chicken breast halves

2 tablespoons olive oil

1 red onion, minced

2 tablespoons lime juice

1 avocado, diced

Salt and ground black pepper to taste

Stir 1 teaspoon salt, 1/4 teaspoon black pepper, and cayenne pepper together in a small bowl; rub evenly into the chicken breasts.

Heat the olive oil in a skillet over medium heat; cook the chicken in the heated oil until no longer pink in the center and the juices run clear, 5 to 7 minutes per side. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).

Stir the onion, lime juice, and avocado together in a bowl; season with salt and pepper. Spoon over the chicken breasts to serve.
