In a large bowl, combine the ground chicken or turkey, breadcrumbs, green onions, mayonnaise, Dijon mustard, garlic powder, onion powder, paprika, salt, and pepper. Mix until well combined.
Form the mixture into 4 equal patties.
Preheat a grill or skillet over medium heat. Cook the patties for about 5-6 minutes on each side, or until they reach an internal temperature of 165°F.
While the patties are cooking, lightly toast the sandwich rolls on the grill or in a toaster.
Assemble the sandwiches by placing a patty on each roll, then topping with shredded lettuce, tomato slices, and pickles.
Drizzle with hot sauce if desired, then close the sandwich and serve immediately.
