Step 1

Preheat oven to 375 degrees F.

Step 2

Spray a 9 inch cake pan or pie tin with cooking spray. Place one of the tortillas in the bottom, letting the edges go up the sides if the tortilla is a bit bigger than the pan.

Step 3

Spread about half of the refried beans on the tortilla, then about a third of the salsa.

Step 4

Distribute about half of the corn evenly on top.

Step 5

Spread out a handful of the spinach and top with about a third of the cheese.

Step 6

Place the second tortilla on top. If the tortilla is larger than the pan, trim the edges so that it fits better (it doesn't need to be perfect, though).

Step 7

Repeat layering with the remaining beans, another third of the salsa, the remaining corn, the remaining spinach, and another third of the cheese.

Step 8

Place the third tortilla in the pan and trim edges if needed. Top with remaining salsa and cheese. Sprinkle with green onion.

Step 9

Bake for 25-30 minutes.
