slow cooker meatball sub sandwiches

Slow Cooker Meatball Sub Sandwiches are the ultimate comfort food! They’re hearty, flavorful, and oh-so-satisfying. Plus, they’re super easy to make in the slow cooker, which means you can spend less time in the kitchen and more time enjoying your meal.

Being a single mother with two very active kids, sometimes trying to eat on the go is hard. Coming home from work, having 45 minutes and then having to leave again to drive 10 minutes to drop off one and then another 30 minutes to drop off another one makes it hard to make dinner. Or at least make dinner that is good for the kids, within the budget and something they will eat!

I try to make food items that my kids can heat on the go. Homemade Slow Cooker Meatball Sub Sandwiches are one of my daughter’s favorites dinners.  And, it is one that she can make as we walk out the door.

I do try to make my own meatballs. Knowing what is in my kids food is a plus for me. I also like rolling the meatballs!
