It’s not easy to eat healthy, especially when subs and sandwiches are involved. That bread is delicious, but it can also throw off a diet in no time. Why not try these Simple Bell Pepper Meatball Subs! They have all of the flavors of a traditional sub with none of the guilt!

Why a Bell Pepper?

Bell peppers are a natural choice to create a low carb or keto sandwich like this. They are low in carbs and have a sweet neutral flavor. Plus, they are sturdy and can hold whatever you choose to fill them with. I have even used them in these Cheesesteak Stuffed Peppers and they are just delicious!

How to Make Simple Bell Pepper Meatball Subs

The biggest part of this recipe is making your own meatballs. I love to make my own, but if you wanted to skip that you could purchase frozen low carb meatballs too.

Once the meatballs are cookied pour a jar of marinara sauce over the meatballs and heat for a few more minutes. While they are heating you can place your cut bell peppers on a baking sheet and top them with a little olive oil, salt, pepper, and a piece of provolone cheese. Just pop them in the oven for the cheese to melt, and if you time it right your peppers will be coming out just in time to be topped with some hot meatballs.
