Mix the top 11 ingredients together until well blended. Using your hands is the best way. Set aside.
In a separate bowl, mix together the feta, oil, salt and pepper with a fork. Set aside.
Make meatballs out of meat mixture, about 3 oz. (10 meatballs)
Make 10 little balls out of the feta mixture, evenly about 1 oz each.
Take a meatball and flatten the ball half as thick as the original ball.
Place the feta ball on top.
Push up the sides of the meat until the edges of meat cover the feta ball completely.
Make the meatball nice and round placing between both palms and rolling it around to tighten the meat and making it smooth. Like you are playing with playdough.
After all 10 are finished, in another skillet, brown meatballs until all sides are browned on medium heat so they do not burn.
Add meatballs to the sauce and cover them in sauce.
Let cook on simmer for another 20 minutes.
If the sauce starts to evaporate, add a little water to maintain a thick consistency.
Remove meatballs onto a platter.
Put sour cream or heavy cream in sauce and whisk to blend.
Blend in ½ c parmesan cheese, vodka, and blend.
Add back the meatballs.
