I pre-made meatballs for dinner and then realized I made them too spicy for the youngest kid who won't eat anything spicy. So now I need to make 5 more meatballs especially just for him. My question is I don't want use a whole egg just for 5 meatballs, what can I use as a substitute so they won't fall apart when cooked? I used breadcrumbs and egg for the other ones, what should I use? Pls help quick answers?
