A Recipe Question...

Okay, I have a recipe question for any who would like to help me in my struggle to cook vegetarian. Tonight we are having a friend over for dinner who doesn't touch anything that clucks or moos, nor can it have a tail or fin. 

Being that I am already somewhat challenged in the kitchen, I was wondering if I can tell you what I have to work with and then you might be able to offer up a suggestion as to how to whip it together into something tasty. Does this sound like fun or do you want me to go away?

So, here goes. The ingredients that I have on hand are -

tortillas

black beans

refried beans

onions

tomatoes

red, yellow, and green peppers

brown rice

garlic

green chiles

green chile sauce and enchilada sauce

Any and all suggestions would be appreciated...
