In a small bowl, lightly beat the egg with a fork until combined.
In a large mixing bowl, combine the ground turkey, beaten egg, panko breadcrumbs, onion powder, paprika, parsley, salt, and pepper.
Lightly oil your hands and gently mix until just combined. Avoid overmixing to keep the sliders tender.
Divide the mixture into 8 equal portions.
Roll each portion into a ball, then flatten into small slider-sized patties.
Heat a grill pan, skillet, or outdoor grill over medium heat.
Cook the patties for approximately 3 minutes per side.
Use a meat thermometer to ensure the internal temperature reaches 160°F (71°C).
During the final minute of cooking, place a slice of cheese on each patty and allow it to melt.
Toast the slider buns if desired.
