Black Bean and Zucchini Chilaquiles

This is a vegetarian recipe I got off my favorite recipe website (epicurious) that was just phenomenal! And super fast to make. I highly recommend :)

1 1/2 tablespoons light or extra-virgin olive oil
1 cup chopped onion
1 medium green bell pepper, diced (I threw two peppers in cause I had them)
One 28-ounce can crushed or puréed tomatoes
2 teaspoons chili powder
1 teaspoon dried oregano
1/2 teaspoon ground cumin
One 16- to 20-ounce can black beans or 2 1/2 cups cooked black beans (from about 1 cup dried)
1 medium zucchini, quartered lengthwise and thinly sliced (I used a yellow zucchini)
1 small fresh hot chile pepper, seeded and minced, or one 4-ounce can chopped mild green chilies (I ommitted this cause my kids freak out over anythiung spicy)
12 6-inch corn tortillas, torn or cut into several pieces
8 ounces grated Cheddar cheese or Cheddar-style nondairy cheese (I used minimal cheese, a small handful for each sprinkling and it was still great!)

1. Preheat the oven to 400° F. Lightly oil a 9- by 13-inch baking pan or 2-quart round casserole.

2. Heat the oil in a large saucepan. Sauté the onion until translucent. Add the bell pepper and continue to sauté until it has softened and the onions are golden. Stir in the tomatoes, seasonings, beans, zucchini, and chile pepper. Bring to a simmer, then simmer gently for 5 minutes.

3. Layer as follows in the prepared pan. Half the tortillas, half the tomato black bean mixture, and half the cheese. Repeat. Bake for 15 to 20 minutes, or until the cheese is bubbly. Let stand for 5 to 10 minutes, then cut into squares or wedges to serve.
