Creating Grilled California Avocado Chicken is simple if you follow these straightforward steps:

1. Prepare the Marinade: In a small bowl, mix olive oil, lime juice, chili powder, garlic powder, onion powder, salt, and black pepper.
2. Marinate the Chicken: Place the chicken breasts in a large resealable bag. Pour the marinade over the chicken, ensuring it is well coated. Seal the bag and refrigerate for at least 30 minutes, or up to 2 hours for more flavor.
3. Preheat the Grill: Preheat your grill to medium-high heat (about 375°F to 400°F).
4. Grill the Chicken: Remove the chicken from the marinade and discard the marinade. Place the chicken on the preheated grill and cook for 6-7 minutes on each side, or until the internal temperature reaches 165°F.
5. Prepare the Avocados: While the chicken is grilling, slice the avocados in half, remove the pit, and scoop out a bit of the flesh to create a small bowl.
6. Grill the Avocados: Place the avocado halves cut side down on the grill for about 2-3 minutes until grill marks appear and they are slightly warmed.
7. Serve: Remove the chicken and avocados from the grill. Fill each avocado half with sliced grilled chicken.
8. Garnish: Sprinkle fresh cilantro over the top and serve with lime wedges on the side for an extra burst of flavor.
