Tuna Green Beans with Harissa Yogurt Sauce

Pairing canned tuna with crisp vegetables creates a swift, balanced meal that leans on pantry staples without feeling plain. Here, snap-tender steamed green beans meet flaked tuna warmed gently in olive oil, all brought together under a sharp, smoky harissa yogurt dressing. The yogurt sauce provides a cool, tangy counterbalance to the warmth of the harissa and garlic, coating the beans and tuna lightly rather than weighing them down.
Why this one works
- Relies on simple canned tuna and fresh produce for quick assembly.
- Steaming keeps the green beans vibrant and pleasantly snappy.
- Harissa paste adds warmth and depth without requiring extra spice blends.
- Greek yogurt makes a rich, creamy sauce base with minimal effort.
- Works nicely served warm from the skillet or at room temperature.

What you’ll need
- 1 lb (450g) fresh green beans, trimmed Trim the stem ends and drain thoroughly after steaming so excess moisture does not dilute the oil or sauce.
- 2 cans (10 oz / 280g) wild-caught tuna in water, drained Press out excess water before adding to the pan so the tuna flakes warm cleanly without becoming soggy.
- 1/2 cup (125g) Greek yogurt Plain Greek yogurt provides a thick, creamy consistency that clings nicely to the warm beans.
- 2 tbsp (30g) harissa paste Adds mild-to-medium heat, roasted pepper flavor, and vibrant color to the yogurt base.
- 1 tbsp (15ml) extra virgin olive oil Used to gently heat the tuna and coat the beans for a glossy, tender finish.
- 1 clove (5g) garlic, minced Mince finely so it distributes smoothly throughout the yogurt without creating harsh raw pockets.

A few things worth knowing
- Keep a close eye on the beans while steaming to preserve their bright green color and slight crunch.
- Flake the tuna gently into bite-sized pieces rather than mashing it, allowing it to hold its texture alongside the beans.
- Drizzle the yogurt sauce over the dish on the platter rather than in the hot skillet to prevent the dairy from separating.
Ways to make it your own
- Scatter fresh flat-leaf parsley or toasted sesame seeds over the top before serving.
- Add a light squeeze of fresh lemon juice over the finished platter for extra acidity.
Serving suggestions
This dish makes a complete light meal on its own, but it also pairs naturally with warm pita bread, boiled baby potatoes, or a bed of cooked couscous to catch the spiced yogurt sauce.
Storage & reheating
Store any leftovers in an airtight container in the refrigerator. For the best texture, keep the harissa yogurt sauce in a separate container from the bean and tuna mixture if preparing components ahead.
