Begin by thawing your chicken breast. Then once your meat is thawed, gather your desired vegetables, wash them, and allow them to dry. Slice all your vegetables as thin as you are able. Gather your remaining ingredients. Now it is time to create.
Preheat oven to 425°F
Taking your chicken, be sure it is cut into the size of your desired proportion for one person. Then slit your chicken, leaving at least ¼ depth of the chicken intact and placing your slits about ½ inch apart, across the entire chicken breast. Place your chicken into a greased baking dish, then drizzle with olive oil.
Insert your sliced vegetables into the slits of your chicken. If you have enough room, it often works best to insert one slice from each type of vegetable into one slit.
Melt butter and drizzle on top of your assembled chicken. Top with minced garlic, Italian seasoning, garlic powder, and garlic salt as desired. Cover and bake for 15-20 minutes.
Remove chicken from the oven and check the internal temperature of the chicken. It should be getting close to 165°F. Top with Mozzarella cheese and bake an additional 5-10 minutes. Cheese should be starting to turn golden in places, and your internal temperature must reach at least 165°F. Once your chicken is fully baked, remove it from the oven, and serve hot. Enjoy!
