Beef and chili burritos

I had a college roommate whose family came to visit and made this delicious concoction for dinner. It is SO good. I don't make it much any more, my kids won't eat this either. I think this is another meal I'm going to go ahead and make for me, then freeze.

Beef and chili burritos:
1 lb ground beef, browned and drained
1 onion dice and cooked with the meat - if using store-bought chili
1-2 cloves of garlic, also cooked with the meat - if using store-bought chili
2 regular cans of chili (I make my own and use 2 cups or so of it instead.)
1 can of mushrooms (really doesn't matter if it's the small or large can. One is 4 oz and the other is 8 ozs., so it will depend on how much you like mushrooms.)
1 can of black olives, sliced (Regular size can, not the little one.)
1 med onion, diced
1-2 tomatoes, diced
Shredded cheese - your choice. I usually use cheddar or jack
Sour cream
Splash of red wine vinegar (opt)
Flour tortillas - Burrito size

Brown meat and vegies if using canned chili. Drain, add chili, mushrooms and olives. Heat well on low. Place other ingredients in individual bowls to pass around as people make their own burritos.
Heat tortillas in microwave, covered with damp towel to keep warm.

When ready to make:
Place warm tortilla on plate. put 2 tablespoons of meat/chili mixture down center of tortilla. Add a tablespoon or two each of tomatoes, onion, shredded cheese and sour cream. Sprinkle with a little red wine vinegar. Fold ends up toward middle - about 1/3 each side. Then fold each side over about 1/3 to make an enclosed package. Now it's ready to eat. YUM-YUM!
