Steps
1. Heat the vegetable oil in a skillet over medium heat.
2. Add the cooked pinto beans and fry them, stirring occasionally, until they thicken slightly and develop a rich flavor, about 5-7 minutes.
3. Season the beans with salt to taste.
4. Warm the corn tortillas on a separate dry skillet or directly over a low flame until soft and pliable.
5. Plate the fried beans and sprinkle the crumbled semi-dry cheese over them so it softens slightly.
6. Serve with two warm corn tortillas on the side.
7. Add a slice of ripe avocado to the plate.
8. Optionally garnish with chopped cilantro or a squeeze of lime for added freshness.
