Simple bread spread with refried beans is Mexico's most humble and beloved snack. This vegetarian, family-friendly dish is a fresh, budget-friendly comfort food for any time of day.
Cut the crusty rolls in half horizontally and lightly toast them on a dry skillet over medium heat for 2-3 minutes until just golden.
In a saucepan, warm the refried beans over medium-low heat, stirring occasionally to prevent sticking; add a splash of water if they get too thick.
Drizzle 1 tablespoon of olive oil into the beans and season with kosher salt and black pepper; stir well and cook an additional minute until fragrant.
Generously spread the warm refried beans over each toasted bread half while the bread is still warm for best absorption and texture.
Top with crumbled queso fresco and finish with the remaining olive oil drizzled over the beans. Serve immediately.
