Peel the onion and slice it into thin strips. Wash the bell peppers, remove the seeds, and slice them into long, thin strips.
Add 1 tablespoon of oil to coat the bottom of a large skillet. Add the Beyond sausage and cook over medium-high heat, turning often, until the sides brown and the sausage firms up. (This takes about 5-7 minutes.) Remove it from the skillet and set aside.
Add the onion and a sprinkle of salt, and sauté over medium-low heat until translucent. Add the sliced bell peppers and sauté until all are soft.
Add the sausages back to the skillet with the onions and peppers and cook for an additional 2-3 minutes until warm. (You can season with a dash or two of Italian seasoning mix and/or red pepper flakes, or a dash of cayenne pepper, for a little spice if you wish.)
Serve on a warm roll, wrapped in a tortilla, or over rice.
Notes
If you are not using Beyond Sausage, sauté the onions and peppers first, then add the vegan sausage links toward the end of cooking, since they only need to warm up, not cook through. You may want to double the olive oil since the sausage does not contain as much oil.
You can serve these sausages on a hot dog roll, cut a baguette, or cut the link in half and serve it on a bun.
We love making this when we go camping or travel with access to a kitchen, since it's easy to prepare and requires only a few basic ingredients.
