Preheat oven to 400ºF.

Trim the tortillas to fit a 9-inch springform pan. Discard the excess or save it to make tortilla strips for salads or soups.

Heat the olive oil in a large skillet over medium heat. Add the onion, jalapeños, and garlic and cook until softened, 5-7 minutes. Stir in the cumin and chili powder and cook about one minute, until fragrant. Add the zucchini to the skillet and cook until just beginning to soften, about 3 minutes.

Increase the heat to high and add the beans, corn, and beer. Once the mixture reaches a boil, reduce heat to medium and simmer for 10-15 minutes, until the beer has thickened and has almost evaporated. Stir in the olives and season to taste with salt and pepper.

Place a tortilla on the bottom of the springform pan. Top it with ¼ of the veggie mixture, ½ cup of cheese, and another tortilla. Repeat with each tortilla; top the last layer with a cup of cheese. Bake for about 20 minutes, or until the cheese has melted and is just beginning to brown. Cut the pie into 6 wedges and serve with cilantro, green onions, lime wedges, salsa and/or sour cream.
