Preheat your oven to 375°F and lightly grease a mini-muffin tin with the olive oil.
Finely chop the fresh spinach and onion into very small pieces to ensure even distribution.
In a large mixing bowl, combine the ground turkey, egg, Greek yogurt, almond flour, and parmesan cheese.
Add the chopped spinach, onion, garlic powder, sea salt, and black pepper to the turkey mixture.
Mix thoroughly by hand or with a spatula until all ingredients are well incorporated.
Scoop the mixture into the prepared muffin tin, pressing down slightly to form compact, even bites.
Bake for 18-20 minutes until the edges are golden brown and the internal temperature reaches 165°F.
Let the bites cool in the tin for 5 minutes before removing to serve warm or store for meal prep.
