- Roughly 20 Frozen Meatballs (we used Ikea brand)
- 1 Jar Marinara Sauce
- 1 Half a Chopped Onion
- 3-4 Mushrooms Sliced
- Rolls or Hoagie Subs (we used Kneaders rolls)
- Cheese (Optional)
Mix the meatballs, marinara, and chopped onion in a crockpot. Put on low for 4-6 hours. Add the sliced mushrooms to the crockpot an hour before finishing. Fill rolls with saucy meatballs and enjoy! It heats up well for a leftover meal too.
