This weekly fave takes literally 5 mins to prepare. I buy frozen breaded chicken breasts (at Trader Joe's, Whole Foods, Stop&Shop). It works great with Frozen breaded eggplant slices too - also found at all stores :)
Ingredients:
Pasta sauce of choice
Frozen breaded chicken breasts (or eggplant slices)
Shredded Mozz Cheese
Coat bottom on 9x13 in pan with pasta sauce.
Place chicken on top (4-5 breasts)
Sprinkle with as much or as little mozzerella cheese
Add a little oregano, salt, pepper
(Sometimes I like to add some fresh spinach or kale too - on top of the chicken, before the cheese)
Cook at 350 for about 25-30 mins, until cheese is bubbly. Sometimes I broil for a few mins at end to get cheese browned.
