Stuffed Peppers

I've been experimenting a lot with using ground veggie round instead of beef and I have yet to find a recipe that it doesn't work with.
This is a really good meal and pretty easy too!

Stuffed Peppers
med red peppers, tops cut off and cleaned
1 pk ground veggie round
1 med onion
4-5 mushrooms
3 cloves garlic
1 pk pre-cooked rice (can use any kind)
1/2 cup diced tomatoes
1/4 cup shredded cheese

In a frying pan put chopped onion, garlic, mushroom and cook for about 2 minutes. Then add veggie round and diced tomatoes and rice. Season to taste. I used flavoured rice so I just added some chili powder and s and p. Cook for another 10 minutes and let simmer.
Once fully cooked, fill peppers and top with shredded cheese. Bake in oven for about 30 minutes on 350 degrees.
