We've had them twice this week.
You will need:
Mashed potatoes (we use yellow; they make the best mash.)
Hot sauce (optional)
Toothpicks for pinning tacos flat
Oil for frying
Heat oil over medium or a little less. You don't need much, maybe a half-inch? Microwave tortillas for 30 seconds or so - otherwise they'll tear when you fold them. Spoon on some potato mixture (not too much or else you'll be sad that you can't fit as much cabbage in later).
Fold over and pin with toothpick.
Fry for a minute or so on each side, until goldeny. BE CAREFUL AND KEEP
FLOUR A FIRE EXTINGUISHER A WELL-FITTING LID NEARBY. Hot oil is terrifying.
Remove toothpick, fill with cabbage, squeeze a shload of lime juice on there, add a few drops of hot sauce, and NOM!!!
