Mixing potato with meat is certainly a good way to stretch a buck, and in this case, it gives a whole new twist to something we have all had a million times, in a million different ways. The traditional recipe is simply ground beef mixed with equal parts potato (boiled is fine) and then it's put into a flour tortilla and fried.
Fill a large flour tortilla, then fold it in half and fry the tacos in batches in a little bit of oil until golden on both sides.
When done, garnish with all your favorites. I like shredded lettuce, cheese, a little sour cream, fresh diced tomatoes and hot sauce!
