Combine the first 8 ingredients in a large bowl. Gently, using your hands, work together all the components to distribute the ingredients evenly throughout the meat. Shape the meat into 12 patties.
Heat a pan over medium-high heat and coat the pan with nonstick cooking spray. Once the pan is hot, add the patties and cook for 3 minutes per side. While the patties are cooking, toast your slider buns at 400 degrees Fahrenheit for 3 minutes if desired.
Serve turkey burgers with desired toppings; I opted for spinach, avocado, tomato, and ketchup!
