- 1 spaghetti squash, halved and seeded
- 3 tablespoons extra-virgin olive oil
- 1/4 cup ground vegan sausage (such as Gimme Lean®)
- 1 small onion, chopped
- 1 small green bell pepper, chopped
- 2 cloves garlic, chopped
- 1/2 cup sliced fresh mushrooms
- 1 (6.5 ounce) can tomato sauce
- 1 (6 ounce) can tomato paste
- 3/4 cup water
- 2 tablespoons dried Italian seasoning
- 2 tablespoons brown sugar
- 2 teaspoons sea salt
- 1 teaspoon ground black pepper
- Preheat an oven to 350 degrees F (175 degrees C).
- Place the spaghetti squash cut side down on a baking dish. Fill the baking dish with about 1 inch of water.
- Bake in the preheated oven until the flesh of the squash is tender and the skin is easily pierced with a fork, about 45 minutes.
- After squash goes in the oven, heat the olive oil in a large skillet over medium heat. Stir in the vegan sausage, onion, bell pepper, and garlic; cook and stir until vegetables are tender, 5 to 7 minutes. Add mushrooms, and cook for 3 more minutes. Stir the tomato sauce, tomato paste, water, Italian seasoning, brown sugar, sea salt, and black pepper. Cover and simmer while the squash continues to cook, about 35 minutes.
- Scoop the flesh from the squash onto a plate, and use two forks to separate and fluff up the strands of squash. Top with the sauce to serve.
