Mussels are a 'super green' food that offer tremendous health benefits. In addition to being low–fat, they're an excellent source of protein, omega 3s, iron, zinc, vitamin C and B12. Preparing blue mussels is easy and quick. Rinse them and add to a pot with 1/4 cup of liquid. Cover and steam for five to seven minutes. They can be spiced up for more elegant occasions, or served plain with butter and crusty bread for a weekday meal.
