1 16 ounce can refried beans
1 pound lean ground beef
1 (1.25oz) package of taco seasoning mix
1 TBS vegetable oil
8 6" CORN tortillas (I have used flour tortillas but corn does taste better with this recipe)
8 oz shredded Cheddar cheese

Toppings:
sour cream
chopped tomatoes 
shredded lettuce
chopped fresh cilantro
green onion, diced
guacamole

Heat the beans in a small saucepan over low heat.  
Brown the ground beef.  When cooked through, add the seasoning packet and stir.  Turn on low to simmer.
Place oil a large skillet.
Let the oil heat, then place one corn tortilla in the skillet.
After 15 seconds, flip the tortilla over and let it fry another 15 seconds.
Repeat this process with remaining tortillas, adding oil if needed.
Let tortillas drain on paper towels.
Once all tortillas have been toasted, arrange then on cookie sheets.
Spread a thin layer of beans on the tortillas, followed by seasoned beef, and then cheese.
Bake the tortillas at 350 for 20 minutes.
Top with desired toppings, and slice into pizza wedges.
Serve.
