In a saute pan over medium-high heat, add ground beef and taco seasoning. Cook and crumble until no longer pink.
Using two large parchment paper covered baking sheets, line out tortillas. Spread each with refried beans and sprinkle with cheese. Add a portion of cooked ground beef and another sprinkle of cheese.
Put in oven and bake for 8 minutes.
Working quickly, remove from the oven and add a smear of sour cream. Add lettuce and drizzle with taco sauce. Then fold them all in half to get the taco shape. Serve 2-3 per person.
