If you like shrimp...
Try: Langostino tails. Sold frozen at grocery stores like Trader Joe's, these lobsterlike tails are a low-calorie protein source with four times the energy-maintaining iron of shrimp. A three-ounce serving has roughly as much iron as a hard-boiled egg but five fewer grams of fat. Skolnik suggests subbing the tails for shrimp in a scampi recipe or using them in fish tacos.
