Warm black beans in a saucepan with cumin, paprika, chili powder, salt & pepper. Add a splash of water if needed.
If not already done, roast or cook sweet potatoes until tender (oven-baked, steamed or air-fried).
In a bowl, layer cooked rice or quinoa as your base.
Add black beans, sweet potatoes, corn, tomatoes, red onion and avocado.
Squeeze lime juice over the top.
Finish with chopped cilantro and a sprinkle of chili flakes if you love a little heat.
