Preparation Heat olive oil in heavy large skillet over medium-high heat. Add garlic and stir 30 seconds. Add bell peppers, zucchini, squash, and onion and sauté until crisp-tender, about 8 minutes. Mix in cumin and sauté until vegetables are tender, about 2 minutes longer. Season with salt and pepper. Place beans in large bowl; mash coarsely with fork. Mix in vegetables and cheese. Place tortillas on work surface. Spoon 1/4 of filling down center of each. Sprinkle each with 1 tablespoon cilantro. Roll up tortillas, enclosing filling. Arrange wraps, seam side down, on baking sheet. (Can be made 1 hour ahead. Let stand at room temperature.) Preheat oven to 350°F. Cover wraps with foil. Bake until filling is just heated through, about 10 minutes. Cut each wrap into 2 or 3 sections.
