Preheat the oven to 350°F (175°C). Lightly spray 8x8-inch (20x20cm) baking pan with a cooking spray. Layer the beans and salsa in the prepared baking dish. Spread the cheeses evenly on top. Bake it for about 25 minutes, or until cheese is bubbly and slightly brown. Top with fresh cilantro and serve warm with tortilla chips.
