How to Assemble

1. Using a baking sheet, place down 8 tortillas down, making sure to overlap and hang half over the sides (2 will go on each long side, 1 on each end, and 2 in the middle).
2. Sprinkle the bottom with 1/2 the shredded cheese.
3. Layer over the taco meat, black beans, green chilies, jalapenos, and cilantro evenly over top of the tortillas.
4. Sprinkle with the remaining half of cheese.
5. Gently fold each tortilla towards the middle and place 1 last one in the middle to cover up the remaining gap. Brush the top with olive oil, and place another baking sheet on top - right side up - helping to hold the tortillas down and bake evenly.
6. Place in the oven and bake for 20-25 minutes or until the top is golden brown and crispy.
7. Remove, cut into squares and serve with your desired toppings.
