Combine the Uncle Ben's rice, water, and olive oil in a skillet. Stir to combine. Bring to a boil and reduce heat to simmer.
While the rice is cooking, place the cubed sweet potatoes in a microwave-safe bowl. Cook for 4 minutes. The sweet potatoes should be tender.
Add the cooked sweet potato cubes to the simmering rice, along with the beans. Sprinkle the top with the vegan mozzarella shreds. Cover and simmer for 5 - 7 minutes. Remove from heat and allow to sit covered until the cheese melts.
