Place the olive oil, lemon juice, dijon mustard, garlic, basil, parsley, oregano, and black pepper in a resealable gallon-sized zip-loc bag. Seal and shake to combine.
Clean and cut the chicken and place in the bag. Seal the bag air tight and move the chicken around to coat in the marinade.
Place the bag in the refrigerator and marinate for at least 30 minutes, up to four hours (can prep and marinate overnight).
Heat a grill or indoor pan over medium- high heat. Cook the chicken 4-6 minutes on each side until browned and cooked through. *
Serve with your favorite sides or top with your favorite sauce or salsa.
