Preheat your oven to 400 degrees Fahrenheit. Line a large baking sheet with parchment paper or lightly grease with cooking spray.

In a large mixing bowl, combine the ground turkey, beaten egg, panko breadcrumbs, Parmesan cheese, minced garlic, Italian seasoning, salt, pepper, and fresh parsley. Mix gently with your hands until just combined, being careful not to overmix.

Using your hands or a cookie scoop, form the mixture into 20-24 evenly sized meatballs, about 1.5 inches in diameter. Place them on the prepared baking sheet, spacing them about 1 inch apart.

Bake in the preheated oven for 20-25 minutes, or until the meatballs are golden brown and cooked through, reaching an internal temperature of 165 degrees Fahrenheit.

Remove from oven and let cool for 5 minutes. Transfer meatballs to meal prep containers, dividing evenly. Store in the refrigerator for up to 5 days or freeze for up to 3 months.

To reheat, microwave for 1-2 minutes or warm in a skillet. Serve with your choice of vegetables, rice, pasta, or in a sandwich for a complete high protein meal.
