preheat oven to 425 degrees.
If using tortillas, cut out tortillas into to circles.For the mini muffin version, cut them into 2¼ inch circles. For the muffin sized version, cut them into 3¼ inch circles.
Place circles into the muffin tins. For the mini’s you should get around 72 and the muffin version will give you about 36. If using Tostitos, just place the scoops on a baking sheet.
In a skillet, brown the beef until fully cooked and drain off any fat.
Add the salsa, taco seasoning, and refried beans to the beef. Stir until well combined.
Place about ⅛ cup on the meat mixture into the muffin sized bites or about 1 Tablespoon in the the mini muffin or Tostitos Scoops version. Top the taco bites with shredded cheese.
Bake at 425 degrees for 12-15 minutes until cheese is melted.
Top with additional toppings if desired and serve. I topped them with a little sour cream and chopped cilantro.
