Prepare the filling by combining black beans, sweet corn, paprika, cumin, lime juice, green onions, and salt in a large bowl.

Lay a tortilla flat and add brown rice, the bean mixture, salsa, lettuce, vegan cheese, sour cream, and guacamole.

Wrap the burrito by folding in the sides and rolling it tightly.

Cut each burrito in half and serve warm with extra salsa and tortilla chips.
