Vegetable quesadillas are a tasty and nutritious recipe that children can make. Start by sautéing your favorite vegetables such as bell peppers, onions, and zucchini in a pan. Place a tortilla on a heated pan and sprinkle grated cheese on one half. Add the sautéed vegetables on top of the cheese and fold the tortilla in half. Cook until the cheese is melted and the tortilla is crispy. Cut into wedges and serve with salsa or guacamole.
