4 flour tortillas (10-inch)
1 tablespoon canola oil
1 large onion, diced
2 garlic cloves, minced
1/2 teaspoon ground cumin
Coarse salt and ground pepper
2 cans (15 ounces each) black beans, drained and rinsed
1/2 lb ground beef (you could leave this out and it is just as delicious)
1 1/2 cups water
1 package (10 ounces) frozen corn
4 scallions, thinly sliced, plus more for garnish
2 1/2 cups shredded cheddar cheese (8 ounces)
Preheat oven to 400 degrees. Using a paring knife, trim tortillas to fit a 9-inch springform pan, using the bottom of the pan as a guide. Set aside.
Heat oil in a skillet over medium heat. Add onion, garlic, and cumin; season with salt and pepper. Cook, stirring occasionally, until onion is softened, 5 to 7 minutes.
Add beans and water to skillet, and bring to a boil. Reduce heat to medium; simmer until liquid has almost evaporated, 8 to 10 minutes. Stir in corn and scallions, and remove from heat. Season with salt and pepper.
Fit a trimmed tortilla in bottom of springform pan; layer with 1/4 of the beans and 1/2 cup cheese. Repeat three times, using 1 cup cheese on top layer. Bake until hot and cheese is melted, 20 to 25 minutes. Unmold pie; sprinkle with scallions. To serve, slice into wedges.
