In a large bowl, combine turkey, breadcrumbs, chopped onion, minced garlic, mayonnaise, Worcestershire sauce, egg, salt, and black pepper
Mix ingredients together until well combined, be careful not to overmix
Shape the mixture into patties, this is easier with wet hands
Preheat a grill or stove pan over medium/high heat
Lightly grease the cooking surface with cooking oil or spray
Cook the sliders for about 3-4 minutes per side, or until they reach an internal temperature of 165 degrees F (75 degrees C) to ensure they are fully cooked
Assemble your sliders and enjoy!
