Preheat oven to 375F. Line a cookie sheet with parchment paper and spray with pan release spray.
Combine the taco seasoning, cumin, garlic powder, onion powder, diced jalapeno and cheese in a medium mixing bowl. Mix well.
Add the ground turkey, mix with the spiced until well combined. Tip: use your hands or a electric mixer on low speed for best results.
Beat the egg in a separate bowl. Add to the ground turkey mixture and mix well.
Using a scoop or your hands, make meatballs into balls that are about 1 inch in diameter. Roll into a ball shape using your hands.
Place meatballs on a prepared baking sheet. Cook for 15 minutes, flipping the meatballs halfway through with a pair of tongs to prevent them from burning.
The meatballs are done when they reach a temperature of 165F when tested with a meat thermometer. Enjoy!!
