Pesto tuna with potato salad

Method

1. Put the potatoes in a pan of salted water and bring to the boil. Cover and simmer for 20 minutes, until tender. Drain and rinse under cold water until cold. Roughly chop and put into a bowl with the aïoli and basil. Season to taste and gently mix.

2. Meanwhile, mix the pesto with the olive oil and brush over the tuna steaks. Heat a griddle pan until really hot, add the tuna and sear for 2-3 minutes on each side, until cooked but still a little pink in the middle. Divide between plates and drizzle with a little extra pesto. Serve with the potato salad and cooked green beans.
