Stuffed Peppers

I love Stuffed Peppers but haven't made them in awhile.
Here is the recipe(very easy)
1 box of spanish rice-I use olive oil instead of butter to saute the rice and definitely add the can of tomatoes-use rotel if you like a bit spicier.
Meanwhile, saute 1/2 of a chopped onion, garlic cloves and mushrooms.
cook 1 lb. of hamburger and then mix everything together and add one can of corn. It may need a bit of salt and pepper and spices to your liking.
Cut 3 bell peppers in half and discard the seeds. Lay open in a 9x13 pan and put the filling in the top and fill all around the peppers. Top w/ mozzarella or monterey jack cheese and bake at 350 for 30 minutes.
