Mini Greek Meatballs

1 pound extra lean ground beef
1/2 small onion, minced
1/2 cup very finely crumbled feta cheese (measure after crumbling finely with a fork)
2 cloves garlic, minced (I used 2 tsp. minced garlic from a jar)
1 large egg
1 T extra virgin olive oil, plus more for baking dish
1 T dried Greek oregano
4 tsp. red wine vinegar
1/4 tsp. salt (optional, I used a tiny bit of Vege-Sal)
1/4 tsp. fresh ground black pepper
1 tsp. Greek seasoning (optional, I used Penzeys)

Preheat oven to 400. Use a food processor to chop the onion very finely, then drain if it seems like there is a lot of liquid. (In the photo I used red onion, but any onion will work.)

Combine all ingredients in a bowl, then use your hands to mix ingredients.

Lightly oil a 9 X 13 baking dish. Shape meat into 1 tablespoon size meatballs and place on baking sheet. Bake 20 minutes, after which time you will see some liquid oozing out. Turn meatballs and bake 10 more minutes. Turn again, and bakd 5-10 more minutes, until meatballs are well-browned and cooked through.

Meatballs are delicious served with Tzatziki Sauce.
