Easy Crock Pot Sandwich Recipe
Having an easy to make recipe like this Crock Pot Meatball Sub recipe helps me get everything done for the holidays and have a great meal on the table for my family.
This recipe has only 4 ingredients and as long as you have a crock pot, and who doesn't these days you can have dinner on the table in under 4 hours if you are in a hurry or it can cook for the standard 8 hours in a crock pot on low.
If you plan to be out all day at work or running around this is a perfect recipe.
It will feed a family of 4 to 6 easily.
So I like to stock the freezer with ingredients from the frozen and dairy section of the grocery store.
Keeping ingredients on hand with a well-stocked freezer is the only thing that gets me through this time of year with my sanity still intact.
Using the crock pot is the second sanity saver I have.
Throw all the ingredients in and I don't have to worry about what I am going to do about dinner.
Frozen Meatballs
Frozen foods can save you money and are packaged in perfect portions for my family.
Frozen Foods make my life easier.
This easy crock pot recipe for meatball sub sandwiches only has 4 ingredients.
A bag of frozen meatballs, a block or bag of shredded mozzarella cheese, a jar of spaghetti sauce and a package of sub rolls.
There are beef or turkey meatballs, seasoned or unseasoned meatballs. Large meatballs or small meatballs.
The small meatballs would make for a great meatball appetizer instead of serving subs for dinner you could also use this recipe for a holiday meatball appetizer recipe for any holiday party you may be hosting.
Or instead of using sub rolls you could serve the small meatballs on slider buns.
They would be easier to serve and handle at a holiday gathering.
Turn the crock pot on high. Pour ⅓ of the jar of sauce into the bottom of the crock pot.
Add the entire bag of frozen meatballs then pour the rest of the sauce over the meatballs.
Put the lid on the crock pot and cook for about 3 hours, occasionally stirring the meatballs.
Cook meatballs until cooked through the center, about 3 hours.
Once the meatballs are cooked slice the block of cheese and lay the slices over the top of the meatballs.
If using shredded cheese sprinkle the cheese over the top of the meatballs.
Replace the lid.
Continue to cook the meatballs until the cheese has melted.
Serve on sub rolls.

Trying this tonight! I am a huge fan of crockpot recipes for a few reasons. One, because I love preparing a meal and forgetting about it. Two, when the weather is warmer such as today (68 degrees) it's nice having a meal that doesn't make the house hot like running the oven. And three, it's usually such an easy recipe to follow and always tastes amazing.
