Heat oven to 400° F
Place all ingredients into a bowl and using your hands, mix until fully incorporated
Form the mixture into approximately 25 golf ball sized meatballs
Place two oven safe skillets on the stove and turn the heat to high
Add one tablespoon of cooking oil (I've used both olive oil and duck fat) to each pan to melt. Pan is ready when you add a drop of water to it and it quickly sizzles
Carefully place 12 meatballs in each skillet to brown, approximately 2 minutes/side
Remove the skillets from the stove and place them in the oven uncovered on the middle rack for 15 minutes or until their internal temperature reads 155-165° F (cooking time will vary by oven)
Remove from oven, let cool, and serve on a bed of romaine lettuce with tziki sauce (see notes)
