Preheat your oven to 425°F (220°C).
In a large mixing bowl, combine the diced sweet potato, sliced onion, and sliced red bell pepper. Drizzle with olive oil and sprinkle with salt, ground cumin, and smoked paprika. Toss until the veggies are well-coated.
Spread the seasoned vegetables evenly on a large baking sheet. Roast in the preheated oven for about 25-30 minutes, or until the sweet potatoes are tender and slightly caramelized, stirring halfway through.
While the veggies are roasting, prepare your brown rice according to package instructions.
In a blender, combine the raw cashews, water, roasted green chilis, nutritional yeast, cumin, chili powder, salt, garlic, and distilled white vinegar. Blend until smooth and creamy.
Once everything is cooked, assemble your burrito bowls starting with a base of brown rice, then topping with the roasted veggies, black beans, sliced avocado, and a drizzle of vegan queso. Finish with a scoop of restaurant-style salsa.
