Preheat oven to broil and grease a baking sheet. Combine all of the meatball ingredients in a large bowl and mix with your hands or a wooden spoon. Use a mini ice cream scoop to scoop meatballs into round balls.
Place on prepared baking sheet and broil for 9 minutes, then flip and broil for 2 more minutes on the other side.
To make the sauce, add the oil, butter, and garlic to a large skillet or frying pan. Cook for 1 minutes or until garlic is fragrant.
Whisk in flour until dissolved. Then add chicken broth and lemon juice. Let simmer.
Add in capers, lemon zest and parsley. Cook for another 5 minutes on low heat.
Add meatballs to the sauce and cover with a lid to finish cooking for 5 more minutes.
