Don’t have mince?
For ease I normally just use mince as it’s so easy to buy. And I find myself often choosing chicken or turkey but when I make them with pork I always vow to make them with pork again next time. Anyway, if you can’t find mince, you can of course just blitz the meat in a food processor - add all the ingredients and blend to make a bit of a paste which you then roll into balls. For example, I think this amount of mince would probably be the equivalent of about 6 boneless, skinless chicken thighs.

Polenta
Very important to look at your polenta packet and see which kind you got. Hopefully the quick cook kind as then it will only take about 5 mins. But regardless, I always use a mix of milk and stock as it just makes it the most flavourful. Season it well and add butter and parmesan at the end (or a cheese of your choice). Honestly if you’re on the fence about polenta or just haven’t had it for a while, give it another chance because it’s so convenient and really truly very delicious when cooked right.

What else could you serve it with?
I am obsessed with the combination of meatballs, tomato sauce and buttery rice. It’s so good - maybe it’s a childhood thing but I love it so much and this works beautifully with rice. See also: mashed potato. Cauliflower mash would also be lovely as would any kind of spaghetti. Or I have to say sometimes I have a bigger portion of the meatballs and tomato sauce and have it with some roasted broccoli or sautéed greens. Also very good.
