Cook rice per directions. Season with cumin.
Add black beans, sweet potato, and seasonings to a pot. Bring to high heat and reduce to low, simmering until sweet potatoes are soft.
Add greens, cover and cook for 5 more minutes. You may need to add a splash of broth or water if it's too dry. Keep heat low to prevent this.
Mix all salsa ingredients together and chill for 10 minutes.
Layer rice, beans, cheese, salt and toppings to taste!
