If making your own parmesan crisps, do this first.
Heat veggie oil (2 tablespoons) over medium heat in a large skillet.
Once shimmering add chopped onion (1 cup) and saute until it begins to soften about 3-5 minutes.
Stir in the spices: chili powder (1 tablespoon), cumin (2 teaspoons), oregano (2 teaspoons), coriander (1/2 teaspoon), and garlic powder (1/2 teaspoon) and continually stir as they toast, until they become fragrant (about 30 seconds).
Add ground turkey (1 pound) to the skillet and break up the meat with the back of your spoon as it cooks. Cook until it's only slightly pink in the center, about 3 minutes.
Add tomato sauce (8 Ounces), vinegar (1 1/2 teaspoons), brown erythritol (1 1/2 teaspoons), and pepper (1/2 teaspoon) and cook until the sauce thickens and coats the meat -- about 4-6 minutes.
Taste and adjust seasonings to your liking (keep in mind, parmesan crisps are VERY salty, so if you find the meat under-salted that's good for most palates!).
Spoon taco meat over your parmesan crisps (see notes below*, you can do this in the snack sized bags of ParmCrisps like I did, a clear plastic cup, or even a mason jar/bowl if you don't need these to be disposable).
Sprinkle with toppings of choice, and enjoy!
