Place a large, deep stockpot over medium-high heat. Once hot, add 2 tablespoons of the olive oil into the pot, followed by the diced onions, celery, bell peppers, jalapeno, and garlic. Stir well and cook for 6 minutes. Stir frequently.
Add in the cajun seasoning blend, garlic powder, onion powder, dried thyme, poultry seasoning, dried bay leaves, and the 1/4 teaspoon kosher salt. Cook for 30 seconds, stirring constantly.
Now add in the vegetable stock, the entire can of crushed tomatoes, vegan Worcestershire sauce, Tabasco hot sauce, and uncooked whole-grain brown rice. Stir well and bring the mixture up to a simmer.
Once it has come to a simmer, turn the heat down to medium-low/low, cover, and continue simmering for 45 minutes. Stir occasionally.
When the jambalaya has about 10-15 minutes left of cooking, place a large saute pan over medium heat. Once hot, add in 1 tablespoon of the olive oil, followed by the vegan chicken and sausage pieces.
Season the vegan meat with the other 1/2 teaspoon of salt and all of the pepper. Saute until the meat is lightly golden brown, about 8 minutes or so.
Then, once the jambalaya has finished simmering for the 45 minutes, add the cooked vegan chicken and sausage into the pot, stir well, cover, and cook for another 15 minutes. Stir occasionally.
Lastly, remove the bay leaves from the pot and discard them.
Garnish your serving of jambalaya with lots of chopped green onions and more Tabasco!
