Place turkey, egg, oats, spinach, green onions, minced onion, salt, and pepper to taste in a bowl. Mix gently to combine. Form into 6 larger or 8 smaller patties.

Heat a skillet that has a lid over medium-high heat and add the oil. Place the patties in the skillet a few at a time; you may need to do this in 2 batches. Sauté the patties until lightly browned, about 5 minutes, then flip and cover with the lid, cooking an additional 3 minutes.

Serve topped with your favorite toppings.
