Tortilla and Black Bean Pie

My Tortilla and Black Bean Pie isn't as pretty as Martha's but I am sure that it tasted just as good, my springform pan was larger then the tortillas I had in the house.  Basically this is a large bean and cheese burrito not rolled up.  

4 flour tortillas (10 inches)
2 tablespoons canola oil
1 large onion, diced
1 jalapeno chile, minced (remove seeds and ribs for less heat)
2 garlic cloves, minced
1/2 teaspoon ground cumin
Coarse salt and freshly ground pepper
2 cans (15 ounces each) black beans, drained and rinsed

1 1/2 cups water
1 package (10 ounces) frozen corn
4 scallions, thinly sliced, plus more for garnish
8 ounces cheddar cheese, shredded (2 1/2 cups)

 

Preheat oven to 400 degrees. With a paring knife, trim tortillas to fit a 9-inch springform pan. Use the bottom of the pan as a guide. Set aside.

Heat oil in a large skillet over medium heat. Add onion, jalapeno, garlic, and cumin; season with salt and pepper. Cook, stirring occasionally, until softened, 5 to 7 minutes.

Add beans and water, 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. Taste and adjust for seasoning.

Fit a trimmed tortilla in bottom of springform pan; layer with 1/4 of the beans and 1/2 cup of cheese. Repeat three times, using 1 cup cheese on top layer. Bake until cheese melts, 20 to 25 minutes. Remove side of pan; sprinkle pie with scallions. To serve, slice into wedges.
