looking for a super easy slow cooker meal? you need to try this slow cooker stuffed pepper casserole! filled with quinoa, rice, vegan sausage, peas, onions, peppers, and lots of flavor.

This slow cooker stuffed pepper casserole is of course so easy to make and so full of flavor. I wanted to take all the flavors of a stuffed pepper combined with the ease of slow cooking. There is rice and quinoa which is cooked in the vegetable broth and tomato sauce. It absorbs all the amazing flavor from the peppers, onions, and vegan sausage.

Stuffed Pepper Inspiration
There are a bunch of different ways to make stuffed peppers. I basically went with the way my mom and family makes them, which is the Italian way. In hers she will usually do peas, rice, and beef. I decided to use both rice and quinoa for two different textures. I also used Field Roast Mexican Sausages since that was what I had on hand and they are very flavorful. If you want to use a vegan ground beef you definitely can.

The Rice
You want to make sure you are using a short grain rice for this recipe. It needs to be able to cook relatively quickly because the quinoa cooks fast. I actually used Kalijira rice which is a very small baby basmati rice. It cooks up very fast so it works well for this recipe. But if you can’t find that just use a short grain white rice.
