Cook the sweet potatoes using an Instant Pot, microwave, or oven. See Instant Pot directions here. To bake in the oven preheat oven to 400 degrees F. Line a baking sheet with foil and pierce the potatoes several times with a fork. Bake for 45-60 minutes until they’re tender when pierced with a fork. To microwave, pierce the skin several times with a fork, place on a microwaveable plate and microwave for 6-10 minutes, rotating halfway through.
While the sweet potatoes are cooking, dice the green pepper and onion.
Heat a large nonstick skillet over medium heat. Add the oil, then the onion. Saute for about 4 minutes, then add the bell pepper and cook for another 4 minutes.
Add in the vegetarian chorizo (or substitute regular chorizo if desired) and cook following package directions. For the Trader Joe’s soy chorizo I just heat it through, mixing in with the onions and bell pepper.
Cut the sweet potatoes across the top, stuff with the chorizo mixture and top with cheese and sour cream.
