Bring a pot of salted water to a boil. While the water is coming to a boil, wash and cut the potatoes into small cubes.
Boil the potato cubes for about 10-15 minutes or until they are soft and break when pierced with a fork. (Cook time will depend on the size of the cubes and your elevation.)
While the potatoes are cooking, peel and dice an onion, then cook it in 3 tablespoons of olive oil and a sprinkle of salt over low heat for about 5 minutes, until it becomes translucent.
Add diced bell peppers, a jalapeño, red pepper flakes (optional), and two teaspoons of Italian herbs to the onions. Turn the heat to medium and sauté for another 5 minutes. Add the vegan sausage, break it up into bite-sized pieces, and cook until it starts to brown.
Drain the cooked potatoes and let them sit in the colander for about 5 minutes to drain off all the excess water. Then, add them to the onions, peppers, and sausage.
Stir well and continue to sauté for an additional 5 minutes. Add salt and black pepper to taste.
Notes
Use frozen potato shreds or frozen potato cubes to avoid the step of cooking your own potatoes if you want a faster meal.
If you prefer a non-spicy hash, omit the jalapeño and red pepper flakes.
