In a large bowl combine onions, mushrooms, parsley, one cup of salsa, oats, egg, garlic powder, thyme, and ground turkey. Give it a hit of salt and pepper and then use your hands to mix everything together until well incorporated.
Lightly coat a rimmed baking sheet with cooking spray.
Using your hands (once again) to free-form six mini meatloaves and place on the baking sheet. Top each loaf with about a tablespoon of the remaining salsa.
Bake for 25 minutes or until cooked through. Enjoy!
