I learned this from my mother who got this from her mother. This might seem weird but you will end up with some great tacos. This recipe is pretty darn flexible, add more or less potato, add more or less cumin or use taco seasoning, different salsa or hot sauce to serve, or even add more toppings! You can't go wrong with more toppings.
This is one of those meals that gets even better the next day. Just reheat a bit in a soft flour tortilla with some cheese and salsa (we prefer Cholula).
Some tips: Cut the potatoes so they will cook quickly but not so small that they will fall apart.
Keep adding cumin until it tastes delicious. —M.McAwesome
