Cut the sweet potato in thick slices and place on a microwave safe dish or parchment paper. Cook for 2 minutes until they are soft but sturdy.
While the sweet potatoes are cooking, brown your grown beef in a sauté pan. Add your spices and salsa and continue to cook for 5 more minutes.
To make individual slices: When potato slices are done, arrange on a plate and top with ground meat mixture and toppings of your choice. I used a bit of avocado, tomato and green onion.
To make a mound of nachos: arrange a big pile of sweet potato chips, then top with the meat mixture and any of the following: shredded chess and sour cream (if you do dairy), guacamole, tomatoes, avocados, green onions, olives, pickled jalapeños, cilantro all work nice.
