Turn your oven to 375°F and preheat it. Coat two baking sheets with a light layer of non-stick spray. Lay out three tortillas on each baking sheet.
02 -
Pop the tortillas in the oven for 3–5 minutes. Flip them over, then bake for another 2–5 minutes until they turn crispy and golden. Set them aside for now.
03 -
Heat up a skillet and cook the beef over medium-high heat. Break it apart as it cooks, then pour off the fat once it's browned.
04 -
Stir the taco seasoning and water into the beef. Bring the mixture to a boil, then lower the heat to medium-low. Let it simmer for 10 minutes, then put it aside.
05 -
Put the refried beans in a microwave-safe bowl and heat them. Using a spatula, put a thin layer of warmed beans across a tortilla.
06 -
Spread a third of your cooked beef on top of the tortilla with beans, then place another tortilla right over it.
07 -
Add 3 spoonfuls of enchilada sauce over the top tortilla. Sprinkle on both types of shredded cheese, then add the chopped tomato, onion, and olives.
08 -
Do the same steps with the other tortillas and toppings to make three full tortilla stacks.
09 -
Bake your tortilla stacks for about 5 minutes, just until the cheese is gooey and starts bubbling. Let them cool for a few minutes, then slice and serve.
