DONE IN UNDER 30 MINUTES!
Heat the oil in a skillet over medium heat. Once hot, add the grated/chopped veggies. Saute the veggies until they are softened, about 8 minutes.
Add garlic powder, chili powder, cumin, and dried oregano. Cook for 30 seconds to combine flavors.
Crumble the turkey meat into the skillet with the veggies and cook, breaking up the meat with the back of a wooden spoon until the veggies and meat are well combined and the meat in cooked through and no longer pink. About 7-10 minutes.
Add tomatoes and salt and cook until most of the liquid in the pan has evaporated, about 5 minutes. Taste for seasoning and add additional salt if desired.
Spoon turkey mixture into the taco shells right before eating and top with desired toppings. Enjoy warm! Allow leftover filling to cool completely before storing in an air-tight container in fridge for 1-2 days.
