What's the best way to reheat meatballs without sauce?

I'm a little late to the game (yes, pun intended), but you could also reheat the meatballs in a slowcooker and they can stay there for the duration of the game.

Thank you!! I think I'll make the yogurt sauce and cook the meatballs and grapes tonight and assemble them tomorrow at room temperature. Go Hawks!

p.s. for leftover grapes, both roasted grapes and frozen grapes are delicious, fun and different!

If you go with room temp, give them 3-4 hrs to get to room temp. If you do want them reheated, put on a sheet pan, covered with foil , in a 350 degree oven for 8-15 min. til temp you want. I don't think that will adversely affect the grapes.

My thought would be to cook and assemble the meatballs and grapes on their sticks, tonight, before you travel. They will taste fine at room temperature (esp. if Seahawks are winning). It will be easier than trying to reheat them tomorrow at someone else's house. You don't want to set the wooden sticks on fire in someone else's oven!
