Wash and chop the spinach.

In a large bowl, mix ground turkey, chopped spinach, feta cheese, garlic powder, onion powder, salt, and pepper until combined.

Divide the mixture into four equal parts and shape into patties about 1 inch thick.

Heat olive oil in a skillet over medium heat until shimmering.

Cook patties for about 5 minutes on each side until they reach an internal temperature of at least 165°F (74°C).

Serve on toasted buns or lettuce wraps with your favorite toppings.
