This gem is a frozen mix of shrimp, calamari and bay scallops and clocks in at only 80 calories for 2/3 cup uncooked. Shellfish are low in fat, full of flavor, and high in omega-3 fatty acids that can be good for a quick meal or a fancy dinner party. We love this blend from Trader Joe’s, which can be easily defrosted and thrown over some chickpea or edamame pasta for a delicious, healthy meal.
