Chop the red onion and celery, dice the red pepper, and mince the garlic. Slice the vegan sausage into coins, keeping the casing on.
Add the oil to a large frying pan and bring the heat to medium high. Cook the onion and garlic for 3 minutes. Then add the celery, red pepper, and sausage. Cook for about 10-15 minutes stirring frequently.
Stir in the rice, kidney beans, tomatoes, soy sauce, oregano, basil, Cajun seasoning, salt, smoked paprika, and Tabasco. Let this simmer for 10 minutes stirring occasionally.
Top the spicy vegan jambalaya with chopped parsley if desired and serve.
