Meatballs like that are usually pork and beef. You can get away with doing anything with them, pizza topping, semi cook them of course. I’m not that savage though, try using Google “beef meatballs” “cuisine” in quotations to look for fancy stuff which might hit different. It will cut the clutter and only give you cuisine from specific countries.
Anyway,
Make a few paper bowls and think about giving some to your neighbours what ever you make. A heavily pregnant person will be much more likely to gain friends or gifts if you are offering them something. They’ll feel obliged to give back! Make sure the bump is visible! You’ll restore their faith in humanity haha
