Then, add diced red bell pepper and jalapeno.
Add Rotel tomatoes and stir (if you prefer it less spicy use a can of diced tomatoes without added heat)
Add red kidney beans, Worchestershire sauce, and herbs and seasoning.
Next, add 4 cups of vegetable broth.
Bring the mixture to a boil.
Add 2 cups of uncooked short-grain brown rice.
Again, bring the mixture to a boil and stir.
Reduce to simmer, and cover, cooking for 25 minutes. See notes; some rice takes longer to cook than others. If the bag of rice suggests longer coking time, follow that time frame).
OPTIONAL: While the vegan jambalaya cooks, grill the whole field roast sausages on medium heat, rotating until done. If you grill the sausage, cut the two sausages into bite-sized pieces after they cool. You can also sauté the pieces in a pan if more convenient.
Cool sausages slightly.
When vegan jambalaya is done, stir, and add sausage for those who wish to eat the vegan sausage.
