The scampi sauce is made of a combination of olive oil, butter, garlic, onions, bell peppers, chicken broth, heavy cream, and Parmesan cheese. This creamy sauce is packed with flavor and is the perfect accompaniment to cooked chicken tenders. The Parmesan cheese adds a salty and nutty flavor to the dish, while the heavy cream helps to thicken it up. The garlic and onions add a subtle sweetness to the sauce.
