Open-faced bean and cheese sandwiches topped with fresh pico de gallo are a light breakfast. This vegetarian, high protein, fresh dish is a healthy, family-friendly morning choice.
Preheat oven to 400°F and line a baking sheet with parchment paper for even heat and easy cleanup.
Slice each bolillo roll in half lengthwise to create four open-faced halves, then lay them cut-side up on the baking sheet.
Spread a generous layer of refried black beans on each cut side, making sure to cover the entire surface for even flavor.
Sprinkle Monterey Jack cheese evenly over the beans, ensuring full coverage to melt properly; bake for 8–10 minutes or until cheese is bubbly and edges are golden.
Meanwhile, mix tomato, red onion, jalapeño, cilantro, lime juice, olive oil, salt, and black pepper in a bowl to make fresh pico de gallo; let it sit for at least 5 minutes to allow flavors to meld.
Once the sandwiches are out of the oven, let them cool for 2–3 minutes, then generously top each with the prepared pico de gallo and serve immediately for best texture.
