Melt half a stick of butter in a saucepan. Cook chicken, garlic, bacon bits, mushrooms, onion and peas until tender and you won't get food poisoning. Season with a bit of salt, onion powder and old bay. .
(Tip: I put my chicken on a George Foreman grill for four minutes to give it those crispy lines, but you can cook it in the pan.).
Move cooked ingredients to the side and mix together half a stick of butter and four tablespoons of flour on low to medium heat (3 minutes) until it resembles a creamy paste.
Stir in two cups of milk and a cup of chicken broth and mix well. Bring to a slow boil. Mix often.
Add one cup of shredded cheese and a cup of grated Parmesan cheese. Get creative! .
Add your other cooked ingredients. Allow to thicken and simmer on low for about ten minutes. Add more milk or chicken broth if you want a thinner sauce or you find the cheese gets stringy.
