This elegant seared tuna with green beans, lemon and wasabi is a sophisticated choice for a light lunch or a quick evening meal. By using sushi-grade tuna steaks and flash-searing them on a hot griddle, you achieve a beautiful contrast between the charred exterior and tender, pink centre. This diabetes-friendly dish is naturally low in carbohydrates but high in lean protein and essential omega-3 fatty acids, making it as nutritious as it is flavourful.
The crisp haricots verts are tossed in a vibrant dressing of zingy lemon, pungent garlic and a hint of fiery wasabi, providing a refreshing kick that perfectly complements the rich fish. A sprinkle of black sesame seeds adds a delicate nuttiness and a striking visual finish. Serve this simple yet impressive seafood dish on its own for a healthy, grain-free dinner.

Ingredients for Seared Tuna with Green Beans, Lemon and Wasabi
4 sushi-grade tuna steaks (90g each)
Salt and freshly ground black pepper
Nonstick cooking spray
350g haricots verts or slim green beans, trimmed
Juice and grated zest of 1 lemon
1 garlic clove, minced
2 tablespoons wasabi paste
4 spring onions (white and green parts), sliced thin on the diagonal
3 tablespoons black sesame seeds
How to make Seared Tuna with Green Beans, Lemon and Wasabi
Bring a large pot of salted water to a boil. Preheat a grill or grill pan over high heat.
Season the tuna steaks with salt and pepper to taste, and spray them lightly with cooking spray. When the grill is hot, add the tuna and cook for 1 1/2 minutes per side for medium-rare. Transfer the tuna to a platter and allow it to rest, uncovered, for 5 minutes.
Meanwhile, cook the haricots verts in the boiling water until they are just tender, about 3 minutes; drain.
In a medium bowl, whisk together the lemon juice and zest, garlic, and wasabi paste. Add the haricots verts, spring onions, and sesame seeds. Toss to coat, adding salt and pepper to taste.
Thinly slice the tuna. Fan each portion onto each of 4 plates. Pile a mound of dressed haricots verts on top of the tuna, and serve.
