Italian Spanish Rice casserole uses up leftovers from other meals fast. Can microwave in a hurry. May make ahead then put in fridge with a lid to heat when you get ready. I threw it together when needed to use up leftovers
Mix the rice and tomato sauce together place in a microwave safe casserole.
Take the hamburger that is mixed with a little bacon drippings (this is ok because the hamburger was 90% lean).
Layer the meat in next.
Layer in the corn then layer the mushrooms.
Then the corn then the bacon for flavor and decoration.
Now the shredded cheese.
Microwave on high 5 minutes or so until heated through and the cheese is melted.
This sounds strange, so if you are a health nut remember that the hamburger was 90% lean and the bacon is for garnish so there is only a little (do not use bacon bits). Did you know you can also add chili beans as a layer if you want. The 1/2 envelope of onion soup might be used to add flavor to the tomato sauce if the sauce is a variety that is boring or bland. Use a little and taste to see if you want to add more or use none if not needed.
