Chistina's Meatball Subs by Jackie

Ingredients
24 frozen meatballs (1 oz. each)
1 jar marinara sauce
6 deli hoagie buns
6 slices provolone cheese

Assembly
Pour meatballs and sauce into gallon-size Ziploc freezer bag.  Freeze upright for easy placement of frozen food into crockpot.  Place buns in 2 separate gallon-size Ziploc freezer bags.  Freeze flat.  Place cheese in quart-size Ziploc freezer bag. Freeze flat.

Serving Day
Thaw meatball bag enough to release into slow cooker.  Running under warm water for a few minutes does the trick.  Cook on low for 4 hours.  (If you'd rather not use slow cooker option, you can thaw contents and cook on stovetop until heated through.)  Toast buns in oven.  Place 4 meatballs and a small amount of sauce on each bun.  Top with a slice of cheese.  Broil 1-2 minutes until cheese melts.  Enjoy!

Variation:
These are very good if you add a few slices of pepperoni to the top of each before adding cheese.

Note for Freezer Friendz:
I did not slice the deli buns, so that you would have the option of doing a regular sub or a boat.  See pic of boat below.  If you want to do a boat, you just need to cut into the top of the bun and scoop out some of the inside bread to hollow it out.
