Place the olive oil, parsley, garlic, lime juice, cilantro, and red pepper flakes (if using) in a blender or food processor and pulse until chopped well. Add more lime to taste as desired. Season with salt and pepper to taste and set aside. (Alternitavely mince the ingredients using a knife and whisk well in a bowl).
Season both sides of the chicken with salt and pepper.
Heat a small amount of avocado oil in a non-stick pan or skillet over medium heat. Cook the chicken on each side until golden brown to an internal temperature of 160°F using a thermometer (about 3-6 minutes on each side depending on thickness). Once chicken is cooked, set aside and allow to rest.
Spoon chimichurri over chicken (about 2-3 tablespoons of chimichurri per portion). Serve with bread. Garnish with fresno chili's.
Notes
Pro tips: Butterfly the chicken: Lay the breasts down on a cutting board, using a sharp knife parallel to the cutting board slice the breasts through the middle (carefully) all the way in half.
