Cook the rice: Cook the brown rice according to the package instructions, using vegetable broth instead of water and a splash of oil. Once the broth is absorbed, fluff and remove from heat. Let the rice rest, covered, while you sauté the vegetables.
Prepare the toppings: While the rice cooks, make the guacamole and fresh salsa, prep/warm the beans, and chop the lettuce.
Grill the vegetables: Sauté the peppers and onions with salt and dried oregano until tender and lightly charred, about 6-8 minutes.
Assemble the bowls: Divide the rice between bowls, then top with the grilled vegetables, beans, romaine, salsa, and guacamole.
Customize and serve: Finish with hot sauce, fresh cilantro, a squeeze of lime, vegan cheese, or your favorite toppings. Enjoy!
