Preheat oven to 375°.
Start cooking rice. See instructions below.
Combine cauliflower, walnuts, onion, bell pepper, celery, and mushrooms in food processor. Pulse until everything is finely chopped.
Add all seasoning (except garlic cloves and parsley) to cauliflower mixture and stir until well combined.
Cover a large baking sheet with parchment paper. Evenly pour mixture onto sheet and bake in the over for 30-35 minutes; stir halfway.
Put rice into a strainer and rinse thoroughly.
Add rice to a pot on the stove and cover with water. You are going to be cooking the rice like you would pasta. This further removes any toxins from the rice and cooks it perfectly.
Let boil on medium heat for 45 minutes or until the rice is at desired textured.
Once it is finished cooking, drain the water and rinse the rice again with a strainer. Put the rice back in the pot and continue with recipe.
When everything is finished cooking, combine rice and cauliflower mixture into large bowl. Add pressed garlic cloves and finely chopped parsley. Stir to combine.
Serve as a side dish or the main course. Top with Louisiana Hot Sauce.
