Hate to use a microwave to reheat meatballs and have heard that some restaurants use a steamer for dry balls but I need to reheat balls in their sauce a portion at a time during off hours. Thought about boil bags, or is gentle stove heating & then covered in the oven 5 mins the way to go?! Want them to hold their shape, be moist, up to temp & be out quick'ish! Am I asking too much?!
