Fresh Tuna & Red Potato Salad

Forget the usual mayo-drenched tuna salad. This version uses grilled yellowfin tuna and red potatoes tossed in a tangy low-fat yogurt dressing spiked with red wine vinegar and ground cumin. It’s lighter, fresher, and works as a real main course.

Grill the tuna first and cut it into 1-inch chunks. You want firm, meaty pieces that hold their shape when mixed with the potatoes, not flaky canned tuna. The red potatoes get simmered whole (or halved) until tender, then cubed. Cutting them after cooking keeps them from getting waterlogged and falling apart in the salad.

The cumin is what makes this dressing unexpected. It adds a warm, earthy note that bridges the tuna and potatoes beautifully. Chopped celery brings crunch, fresh parsley adds color, and the vinegar cuts through the richness of the fish. Chill everything for at least an hour so the flavors come together.

Chef Tips

• Don’t overcook the potatoes. They should be tender but still hold their shape when cubed. A knife should slide in easily but meet slight resistance at the center.
• Grill the tuna to medium-rare or medium for the best texture. Overcooked tuna dries out fast.
• Low-fat yogurt works better than full-fat here. It gives the dressing a lighter tang that lets the tuna shine.
• Cider vinegar is a fine substitute for red wine vinegar if that’s what you have.

Variations

• Mediterranean spin: Add halved Kalamata olives and chopped sun-dried tomatoes.
• Herb-loaded: Stir in fresh dill or chives along with the parsley.
• With greens: Serve over a bed of arugula or mixed greens for extra volume and nutrition.
