In a small bowl or jar, combine the sauce ingredients: Greek yogurt, cucumber, parsley, dill, lemon juice, and grated garlic. Season with salt and pepper to taste, then set aside.
In a large bowl, add the burger ingredients: ground chicken, red onion, oregano, parsley, garlic, feta, breadcrumbs, and egg. Use your hands to thoroughly mix the ingredients.
After mixing, divide the chicken mixture into four equal portions and shape them into patties with your hands.
Preheat a grill or grill pan to medium-high heat, then grill the patties for 5-6 minutes on each side until they reach an internal temperature of 165ºF.
Once the burgers are done, remove them from the grill and assemble them on buns with your choice of yogurt sauce or tzatziki, along with your preferred toppings.
Any leftover burger patties can be stored in an airtight container in the fridge for up to 5 days.
