tracy's tostadas

my recipe for this week is an original...yahoo! i've seen similar recipes, but none that were exactly the taste i was going for so i tried my own. jerry and i both agreed, it's a definite keeper and good enough to share, for sure!! even my vegetarian friends will enjoy this one!
4 soft taco tortillas
1 can black beans (drained, rinsed)
1/2 cup cooked brown rice
1/2 cup frozen corn (thawed)
1 small onion, diced
6 oz mexican blend shredded cheese
shredded lettuce
1 tomato, chopped
sour cream
mix beans, rice, corn, and onion together. place tortillas on a cookie sheet. spread bean mixture equally onto each tortilla, then top each with a handful of cheese. bake in oven at 400 degrees for about 8-10 minutes until cheese is melted. remove from oven and top with lettuce, tomato, and sour cream. cut into 4 pieces and enjoy! if you like extra hot...top yours off with a few jalapenos, like my husband did!
