From Chris Carmichael's "Food for Fitness", p. 292. "This is a recipe that combines two of athletes' favorite vegetables: spinach and black beans. It's a great dish for getting your carbohydrates and your protein, as well as a big dose of vitamins. This can also be served over brown rice, especially since brown rice takes 45 to 50 minutes to prepare. The rice will be ready just as the rest of the recipe is ready."
