Creating your Easy White Cheddar Spinach Chicken Burgers is as simple as following these easy steps:

1. Prepare the Ingredients: Gather all of your ingredients to ensure a smooth cooking process.
2. Preheat the Grill: Preheat your grill or stovetop skillet over medium heat.
3. Combine Ingredients: In a large mixing bowl, add ground chicken, chopped spinach, shredded white cheddar cheese, breadcrumbs, egg, garlic, onion powder, salt, and black pepper.
4. Mix Thoroughly: Use your hands or a spoon to combine all ingredients until well mixed. Make sure not to overmix.
5. Form Patties: Divide the mixture into four equal portions and shape them into patties about 1/2 inch thick.
6. Grease the Grill: Lightly spray the grill or skillet with cooking spray or drizzle with olive oil to prevent sticking.
7. Cook the Burgers: Place the patties on the grill or in the skillet and cook for about 5-7 minutes on each side, or until fully cooked (internal temperature should reach 165°F).
8. Melt the Cheese: In the last minute of cooking, place a slice of white cheddar on each patty to allow it to melt.
9. Remove and Rest: Once cooked, remove the patties from the grill and let them rest for a few minutes.
10. Prepare for Serving: These burgers are now ready for your favorite toppings and buns!
