01 - In a large bowl, combine ground turkey, breadcrumbs, egg, onion, garlic, Worcestershire sauce, smoked paprika, salt, and pepper. Mix just until combined without overmixing.
02 - Divide the mixture into 12 equal portions and shape each into a small patty, approximately 2 inches wide.
03 - Heat a large skillet or grill pan over medium heat and lightly oil the surface.
04 - Cook the patties for 3 to 4 minutes per side until golden brown and cooked through, reaching an internal temperature of 165°F. Remove from heat and keep warm.
05 - While the patties cook, mix mayonnaise and mustard together in a small bowl.
06 - Lightly toast the slider buns, if desired.
07 - Spread a thin layer of the mayo-mustard mixture on the bottom half of each bun.
08 - Place lettuce on the bun, top with a turkey patty, then a slice of cheese if using, a pickle slice, and a tomato slice if using.
09 - Cover with the top bun and secure with a toothpick if needed. Serve immediately.
