Ingredients for 5 stuffed breasts:
Fire up grill to 350F or set oven to 400F.
Set a nonstick skillet on medium heat and add olive oil, garlic, onion and bell pepper. Saute for 1 minute, then toss in mushroom caps and squeeze in lemon. Cook and stir for 3 to 5 minutes until the onions are caramelized and the edges of the pepper are seared. Season to taste with sea salt & pepper.
Season chicken breasts. Slice the chicken down it’s side to create a “pocket.” Do NOT butterfly the chicken, cutting it from top to bottom; slice it more so in the middle in order to create a deep pocket.
Stuff each chicken with grilled veggies and 2 tablespoons of cheese.
Place the chicken on the hot grill and cook for 20 minutes (flipping halfway), or until the juices of the chicken run clear and it is completely white.
Serve immediately while hot; but, you can also eat these while cold, like chicken pizza! These are hearty pieces of protein so chop if them up for more than 1 serving.
