Consider your tuna-noodle casserole obselete. Combine orecchiete pasta (the shallow shells named for the Italian word for "ears") with lemon, dill, peas and tuna for a bright main dish that might shelf that glass baking dish forever. The recipe yields enough for a crowd, making it a perfect option for potlucks.
Sneak carrots and celery into tuna salad on a whole wheat English muffin for lunch the next day. Broil the cheese in the morning before school so it's melted or just lay a slice on top -- either way, the sandwich is mighty tasty for sealegs and land lubbers alike. We also love the use of plain yogurt instead of mayo (or as a partial substitution) to bring up the nutrition and take down the saturated fat.
