Rinse and drain quinoa.
Sautee quinoa on low heat in a medium sauce pan for a few minutes and then stir in 2 cups water.
Cook quinoa uncovered on medium heat until water evaporates (about 15 minutes). Stir frequently to prevent sticking.
Remove quinoa from heat and add to a bowl. Stir in cooked black beans, tomatoes, cilantro, onions and lime juice. Add in spices to taste.
