To start, in a bowl, add in the ground turkey, dill, mint, red onion, garlic, egg, breadcrumbs and the seasoning. Mix everything until combined then cover the bowl and place in the refrigerator for 15-20 minutes.
Preheat the oven to 400℉.
Remove the bowl then form the meatballs into the size of golf balls. In a frying pan with a little olive oil sear a side or two of each meatball then place on a sheet pan.
Place the pan into the oven for 15 minutes. They will not take long to cook after being seared.
When finished, serve the Greek turkey meatballs with crumbled feta cheese and drizzled with tzatziki sauce.
