Tortilla Pie

Ingredients
1 (15-oz) can black beans, drained and rinsed
1 (10-oz) package frozen corn kernels, thawed
1 cup mild tomato salsa
1 (8-oz) can tomato sauce
6 oz pepper Jack cheese, coarsely grated (2 cups)
1/2 cup chopped fresh cilantro
2 scallions, thinly sliced
1/2 teaspoon ground cumin
4 (10-inch) corn tortillas (I used 8 small round since I couldn't find large ones)
1 tablespoon olive oil

Accompaniment: sour cream

Directions

1. Put oven rack in lower third of oven and preheat oven to 450°F.
2. Stir together beans, corn, salsa, tomato sauce, cheese, cilantro, scallions, and cumin in a large bowl.
3. Heat a 12-inch heavy skillet over high heat until smoking. Brush both sides of each tortilla with oil and fry, turning over once, until puffed and golden in spots, about 1 minute.
4. Put 1 tortilla in a well-oiled 15- by 10-inch shallow baking pan, then spread with 1 1/3 cups of filling. Repeat layering twice, then top with remaining tortilla, gently pressing to help layers adhere.
5. Bake until filling is heated through, about 12 minutes. Transfer with a large metal spatula to a platter, then cut pie into wedges with a serrated knife.
