Recipe Information
Ingredients
- 2 pieces boneless skinless chicken breasts
- 2 tablespoons olive oil
- 2 tablespoons lemon juice
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon paprika
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 8 leaves romaine lettuce leaves
- 1 large tomato
- 0.5 medium red onion
- 1 medium avocado
- 4 tablespoons Whole30 compliant mayonnaise
Instructions
In a large bowl, mix olive oil, lemon juice, garlic powder, onion powder, paprika, salt, and pepper together.
Add the chicken breasts to the marinade and coat them thoroughly. Allow them to marinate for at least 15 minutes at room temperature or up to overnight in the refrigerator.
Preheat the grill to medium-high heat.
Once marinated, grill the chicken breasts for about 6-7 minutes on each side, or until fully cooked with an internal temperature of 165°F (75°C). Remove from grill and let rest for 5 minutes.
While the chicken rests, slice the tomato and red onion thinly. Cut the avocado in half, remove the seed, and slice it thinly.
Spread Whole30 compliant mayonnaise on one side of the romaine lettuce leaves.
Slice the grilled chicken into strips.
To assemble the sandwich, take two romaine leaves and place slices of chicken on one leaf. Top with tomato slices, red onion slices, and avocado slices. Place another lettuce leaf on top to create a sub-style sandwich.
Repeat the assembly for the remaining ingredients to create four lettuce-wrapped sub sandwiches.
Serve immediately and enjoy!
