Place 2 x 125g of fresh tuna steaks in a shallow dish and spoon over 2 tbsp of teriyaki sauce. Turn the tuna, coating it on all sides then cover and leave for around 10 minutes to marinate. When you?re almost ready to eat, remove the tuna from the dish and cook on a barbecue or griddle until cooked as you like it. Heat 1 tbsp of sunflower oil in a wok and stir-fry a 3 cm piece of peeled and chopped ginger and 1 crushed garlic clove for a minute. Then add a 300g bag of stir-fry vegetables and stir-fry for around 5 minutes. Add a 400g bag of fresh noodles and 1 tbsp of reduced-salt soy sauce and heat through. Serve the noodles topped with the tuna. Follow with a bowl of raspberries for each person.
