This from my mom - worked really well tonight for dinner. It's sort of like lasagna without the pasta.

Slice chicken breasts into medallions. Put some butter and olive oil in a big pan and saute some garlic and onion in it. Add the chicken and saute until it's almost cooked.

Put chicken/onion/garlic into a baking pan. (I used a glass 9x13 dish) Add some sliced mushrooms (I used baby bella/creminis). Pour a jar of pasta sauce in. Top with fresh spinach and slices of fresh mozzarella. Bake in a preheated 350 degree oven for 25 mins or until liquid is gone (this is why it's good to use a glass pan - you can see how much liquid is left. Although I just poured out excess liquid after 25 mins).

Turn off the oven. Sprinkle with parmesan cheese and put back in until parmesan melts, about 5 minutes. Add salt and pepper to taste. Yum!

What are your ideas?
