Prepare the long grain rice in accordance with the package directions.
Combine the tamari, maple syrup, balsamic vinegar and smoked paprika in a small bowl. Stir to combine and set aside.
Make sure that your onions, celery, garlic, green bell pepper and celery are prepped.
Melt the vegan butter over low heat in a large stockpot. When the butter has melted, stir in the flour.
To make the roux, continuously whisk the butter and flour over low heat. As it cooks, it will darken. Continue cooking until it reaches a rich, dark brown. About 20 minutes. Then remove the roux from the heat and continue whisking it has cooled.
Add the onions, garlic, celery, bell pepper and okra and stir to coat. Add the tamari mixture and return the pot to medium-low heat and cook, stirring frequently, for 4-6 minutes. Be careful not to burn the roux.
Add the vegetable broth, water, diced tomatoes, tomato sauce, salt, pepper, cayenne pepper, thyme, oregano, bay leaves and vegan Worcestershire sauce. Bring the broth to a high simmer, then reduce the heat to a low simmer. Allow to cook, covered, for about 1 hour, stirring occasionally.
After an hour, the soup should be quite thick. Remove the bay leaves and add the vegan sausage to the soup. Heat until warmed through.
Serve the gumbo over a bowl of long-grain rice. Top with Tobasco® sauce and sliced scallions, as desired. Season with salt and pepper, to taste.
