Ponzu tuna steaks recipe with grape and lamb’s lettuce salad

This recipe for ponzu tuna steaks from Kikkoman is a fresh way to enjoy fish for dinner.

Ponzu is a citrus-flavoured sauce that’s commonly used in Japanese cooking. It’s usually made from yuzu, or other citrus fruits, as well as katsubushi (dried fish flakes) and seaweed. But you can make your own simple ponzu-style sauce without any of these hard-to-find ingredients, or you can buy a pre-made sauce.

Finding tuna that’s sustainable can be a tricky business. On the whole, opt for albacore tuna for the most sustainable option, ideally buying those that have been caught buy pole and line. Also keep an eye out for tuna that has been certified by the Marine Stewardship Council. You can find out more about responsible fishing at Seafish and Marine Stewardship Council.

You can also swap the tuna steaks for an alternative like salmon or trout. Both taste great when served in this recipe.

An array of leaves and greens gives the salad a fresh and vibrant appearance. Chicory is a fantastic source of inulin. Inulin is a type of fibre and prebiotic. It helps to feed the good bacteria living in our gut, helping to support our digestive system. Meanwhile, lamb’s lettuce is rich in beta-carotene, which is converted to vitamin A in the body. Vitamin A helps to keep our vision and skin healthy, while also helping to support our immune system.
