topping ideas

guacamole (I made mine with jalapeño, yellow onion, cilantro, lime juice, kosher salt and a tiny bit of garlic powder)
pico de gallo
salsa
lettuce
hot sauce

Preheat oven to 400 F. Lightly oil a large baking sheet, or coat it with a little cooking spray.

Heat the olive oil in a large sauté pan over medium heat and add the onion. Cook until the onion starts to brown, about 5 minutes. Add the chili powder, cumin, salt and garlic and cook for another 30 seconds and then turn off the heat.

In a large bowl, mash together the beans, chilies, and lime juice with a spoon or masher until a paste forms. Leave a few beans un-mashed for added texture.

Fold in the corn and sautéed onions and stir.

Wrap the stack of tortillas in parchment paper and microwave until warm and pliable, about 15 seconds. Heap about 2 tablespoons of the filling and spread in a line toward the edge of the left side of one of the torillas from top to bottom. You can even put a small smear of beans toward the other end of the tortilla to help it stay shut. Tightly roll the tortilla from left to right. Place the flauta seam side down on the baking sheet. Repeat with remaining mixture and tortillas.

Lightly coat the flautas with cooking spray and bake for 10 minutes. Check to make sure the bottoms are golden, if not, continue baking for another couple of minutes. When the bottoms are golden brown, turn them over with tongs and bake an additional 5 to 7 minutes, or until they are golden and crispy on both sides. Serve warm with toppings of your choice.
