Cook Rice according to package instructions.
While the broccoli, sausage and rice are cooking you can sautéed the onion, garlic, and mushrooms. In a large fry pan or skillet add avocado oil, garlic and onions. Cook until translucent about 5 minutes.
Add in the mushrooms and season with salt and pepper to your liking. When that's done remove from the pan and put in a dish until ready to add to the bake.
In the same fry pan put vegan butter and almond milk and whisk until butter is melted.
When the sausage is done slice it and quart it. It should be chunks but you can make them any size you want. When the broccoli, sausage and rice are done, pour the rice, broccoli, and sausage into your baking dish. Pour almond milk and butter mixture on top and mix well.
Mix in the sautéed onions, garlic and mushrooms. Sprinkle the top with your favorite vegan cheese shreds and place back in the oven for another 15 minutes, until the cheese melts.
Serve right away and enjoy!
