2 tablespoons vegetable oil
1 medium onion, finely chopped
2 cloves garlic, minced
3/4 pound lean ground beef
2 teaspoons chili powder
1 teaspoon cumin
1/2 teaspoon salt
3/4 cup water
1 (15 1/2-ounce) can black beans, drained and rinsed
1 1/2 cups frozen corn kernels
4 (10-inch) flour tortillas
1/2 cup sour cream
1 cup salsa
8 ounces Cheddar or Monterey Jack, grated
1.In a large skillet over medium-low heat, warm the oil. Add the onion and sauté for 5 minutes, stirring often. Add the garlic and sauté another minute.
2. Increase the heat to medium, then add the ground beef, chili powder, and cumin. Cook the mixture until the beef is browned and no longer pink, stirring often, about 3 minutes. Add the salt, water, black beans, and corn, and bring the mixture to a boil. Allow it to continue boiling, stirring occasionally, until the liquid evaporates, about 20 minutes. Remove the mixture from the heat and let it cool for 10 minutes.
3.Heat the oven to 350°. Using the rim of a 9-inch spring form pan as a template, trim 3 of the tortillas to the size of the pan. Leave the fourth tortilla untrimmed. Note: You can also bake this dish in a 9-inch round cake pan and serve it like a lasagna.
4.Butter the bottom and the sides of the pan. Press the untrimmed tortilla evenly into the pan’s bottom. Spread 2 tablespoons of the sour cream over the tortilla, followed by 1/4 cup of the salsa. Spoon and spread a quarter of the beef mixture over the salsa, then sprinkle a quarter of the grated cheese evenly over the top.
5. Place one of the trimmed tortillas on top of the cheese, then repeat the layering of the sour cream, salsa, beef, and cheese. Continue this way until the ingredients and tortillas are used up. You should end up with four layers, topped with the final sprinkling of cheese.
6.Bake the pie until heated through, about 30 minutes. Allow it to cool for 10 minutes, then remove the rim from the spring form pan, if you used one. Slice the pie into wedges using a sharp knife. Serves 10.
