Favourite Shell Pasta with Beans & Tuna

This pasta salad earns the “favourite” tag because it pulls double duty: a complete, protein-packed lunch on its own and a sturdy potluck contribution that holds up beautifully overnight in the fridge. Shell pasta cradles the tuna, kidney beans, and chopped olives in their little cupped pockets, so every forkful gets a balanced bite.

The dressing is intentionally minimal. Just red wine vinegar, salt, and pepper, no oil. The tuna and beans bring enough natural fat to keep things from feeling dry, and the lean vinaigrette lets the ingredient flavors stand on their own. Grated Asiago sprinkled in at the end adds a salty, nutty backbone that swaps cleanly for Parmesan if that’s what’s in your fridge.

A pinch of finely chopped red onion gives the salad its sharp edge, while parsley keeps everything looking fresh and bright. Toss everything together while the pasta is still slightly warm, the noodles will absorb the vinegar and onion as they cool, building flavor as they sit in the fridge.

Pro Tips

• Cook the shells just to al dente, they’ll soften further as they sit in the dressing overnight.
• Drain the tuna well and break it into chunks rather than flakes for visual appeal.
• Rinse canned beans thoroughly to remove the slimy canning liquid that throws off the dressing.
• Make this the night before serving, the flavors meld dramatically by the second day.

Variations

• Use chickpeas or white beans in place of kidney beans for a different texture.
• Stir in a half cup of halved cherry tomatoes for sweetness and color.
• Add 2 tablespoons of capers or chopped pepperoncini for a briny Mediterranean kick.
