01 - In a large mixing bowl, combine ground turkey, breadcrumbs, egg, onion, garlic, Worcestershire sauce, smoked paprika, salt, and pepper. Mix just until combined without overmixing to maintain tender patties.
02 - Divide the mixture into 12 equal portions and shape each into a small patty approximately 2 inches wide, handling gently to preserve texture.
03 - Heat a large skillet or grill pan over medium heat and lightly oil the surface to prevent sticking.
04 - Cook the patties for 3 to 4 minutes per side until golden brown and cooked through, ensuring internal temperature reaches 165°F. Transfer to a warm plate.
05 - While patties cook, whisk together mayonnaise and mustard in a small bowl until well combined.
06 - Lightly toast the slider buns if desired for enhanced texture and flavor retention.
07 - Spread a thin layer of the mayo-mustard mixture on the bottom half of each bun. Layer with lettuce, turkey patty, cheese if using, pickle slice, and tomato slice if using.
08 - Place the top bun on each slider and secure with a toothpick if needed. Serve immediately while warm.
