This is a bit different than the usual requests for info on here... I'm seeking a place to get the best meatballs in town but for serving at a party, not for dining in, so I want the meatballs only, plain or covered in sauce already -- either way is fine. If I am adding my own sauce, it will be a marinara sauce. I don't care if the place has amazing or bad pasta or no pasta at all as long as their meatballs are good. Typical party size would be 12-16 people.
Ideally, the meatballs would already be cooked but not necessarily hot. In fact, I'd rather be able to pick them up 3 or more hours in advance of the party, so I am looking for something I can heat up, either from a picked-up-hot, refrigerated, or even frozen state.
So which restaurant, butcher shop, Italian market, grocery store, etc. has wonderful meatballs that I can take home, heat up or reheat, and serve? (I'm not trying to pass them off as I made them -- my guests will know they were bought premade.) If you do recommend frozen from a grocery store or warehouse club, please indicate the brand name as well.
Thanks in advance!
