Steps
1. Heat the vegetable oil in a skillet over medium heat.
2. Add the cooked pinto beans and fry them, stirring occasionally, until slightly crispy and heated through, about 5-7 minutes.
3. Season the beans lightly with salt and remove from heat.
4. Warm the corn tortillas on a clean skillet or comal for about 1 minute per side until soft and pliable.
5. Arrange the fried beans, crumbled semi-dry cheese, warm tortillas, and sliced avocado separately on a plate.
6. Serve immediately, allowing each ingredient to be enjoyed individually or combined as desired.
