Slow Cooker Meatball Subs Recipe

WANT TO SAVE THIS RECIPE?

My parents watched Kayleigh for us overnight last weekend, so John and I actually had some time to relax for a while.  We’ve both been super busy and feeling under the weather for a while now, so it was a much needed break. 

Instead of spending lots of time and energy cooking a big meal, I decided to make some meatball subs using my slow cooker .  My slow cooker has seriously been getting a workout this fall.  I’ve had it for years now, but never really put it to much use until lately.  What was I thinking??  It’s so easy to have a warm and delicious meal ready for dinner time without putting a lot of time and energy into it, and without a lot of clean up. 

I loved how these meatballs came out, and they were so tasty sandwiched in a toasted roll with some melted mozzarella cheese on the top.  We had some leftover sauce and meatballs, and I used them to make a yummy meatball pizza the next day too!
