Creating Keto Spinach Feta Turkey Burgers is simple if you follow these instructions:

1. Prepare Ingredients: Gather all your ingredients and chop the spinach finely. Set aside.
2. Mix the Mixture: In a large bowl, combine ground turkey, chopped spinach, crumbled feta cheese, egg, minced garlic, onion powder, salt, and pepper. Mix well until combined.
3. Form Patties: Divide the mixture into four equal portions, shaping them into burger patties.
4. Cook the Burgers: Heat olive oil in a skillet over medium heat. Once hot, add the patties and cook for about 6-7 minutes on each side, or until golden brown and cooked through.
5. Check Doneness: Ensure the internal temperature reaches at least 165°F (75°C) for safety.
6. Rest the Burgers: Remove the patties from the skillet and let them rest for a few minutes to maintain juiciness.
7. Prepare to Serve: While the patties rest, prepare your serving options (lettuce wraps, tomato, and avocado).

Following these steps will lead to delicious turkey burgers that are both healthy and satisfying!
