All about the meatballs

I have all sorts of appreciation for frozen meatballs.Available at most grocery stores and at Costco (in a gigantic bag), they are one of the most versatile ingredients that you can have in your freezer!

The meal idea possibilities are infinite and making your own make ahead meatballs is a budget friendly alternative to buying the premade, more expensive ones.

For this recipe, you can use premade meatballs, homemade meatballs, thaw them out, or keep them frozen. Whatever works for you!

The slow cooker does the majority of the work and dinner is delicious. These also make a great appetizer. My favorite kind of recipe!

About the Ingredients

  • Meatballs – Fresh, frozen, ground beef or turkey… whatever you want to do here is fine. I keep a bunch of make ahead meatballs in the freezer so this comes together quick and easy.
  • Peppers – This recipe is pretty with multicolored peppers but there is no need to make them with any specific color. I always like to cut up a few pieces into smaller pieces and save them to stir into the finished product. The pepper chunks in the slow cooker will cook down so adding a few small pieces of uncooked peppers at the end adds a nice crunch.
  • Vinegar – This recipe calls for rice wine vinegar (rice vinegar) or apple cider vinegar. I almost always have the seasoned rice vinegar available in my pantry but if you don’t have either of those, you could also substitute plain white vinegar.
  • Soy Sauce – It doesn’t matter if you use low sodium soy sauce or regular soy sauce to make this. Also, I often substitute coco aminos here because the flavor is the same and the product is allergy friendly, contains less salt and is a lot less expensive than soy sauce!
  • What to Serve With – As an appetizer, serve with toothpicks. As a dinner, serve over any kind of rice (absorbs the sauce) or over egg noodles (weirdly good).
