Microwave 2 potatoes in their wrappers on high, 6-8 min, flipping over halfway through cook time (caution, that's a hot potato!); scoop into a bowl, season with salt/pep + mash until smooth; set aside

Stack 4 tortillas on a plate + wrap with a damp paper towel; microwave 15-30 sec or until soft + pliable; spread potatoes onto 1 half of each tortilla, sprinkle with ¼-½ cup cheese, then fold in half to seal

Heat a lightly oiled skillet over medium; cook tacos 2-3 min per side until hot + crispy

Serve crispy tacos with 2 tbsp guac for dipping
