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