In a large mixing bowl, combine ground chicken, whole wheat breadcrumbs, grated Parmesan cheese, finely chopped onion, minced garlic, chopped fresh parsley, dried oregano, paprika, and salt and black pepper to taste. Mix gently until just combined.

Divide the mixture into four equal portions and shape each into patties about ½ inch thick. Make a slight indentation in the center of each patty.

Heat olive oil in a non-stick skillet over medium heat. Once shimmering, place the patties carefully without touching. Cook for about 5-6 minutes on each side until cooked through.

While cooking, split the hamburger buns and toast them in another skillet until lightly golden, about 2-3 minutes.

Once cooked, transfer the patties to a plate and let them rest for a couple of minutes.

To assemble, place a patty on the bottom half of each toasted bun, add desired toppings, and finish with the top bun.
