Young people are hungry all the time. I don't know about your kids but I feel like I need to feed my kids 8 times a day. Have them make a big batch of meatballs so you don't have to hear them say "I'm hungry!" every 5 minutes. I will show you a cheat-way of making meatballs. I've fed these meatballs to sooo many kids and they are always a big hit!
