This isn’t so much a recipe as just a great idea – came across it on Twitter the other day and now can’t remember who posted it. Anyhow, you just take some fresh tuna steaks, lightly salt & pepper them and set aside. Then sautée some spring onion and garlic in olive oil; when nicely browned push to one side of the pan and add the tuna. When the tuna is cooked to your liking splash some soy/soya sauce into the pan, turn tuna to coat in sauce. Done!

Very simple and very tasty.
