Impossibly Easy Leftovers!

I LOVE to turn my leftovers into something new and one of my favorite ways is to turn them into Impossibly Easy Pies. It's just basically a topping made with a mixture of 1/2 cup Bisquick, 1 cup milk, 2 eggs and 1 cup shredded cheese. I've used chili, casseroles, various mixes of meat and veggies and tonight, it's Buffalo Chicken Mac and Cheese! (Don't worry, I froze the leftovers so they haven't been sitting in the fridge for a month!) I've been running around all day so this was the perfect easy dinner, not to mention very satisfying!
