Lemony Rocket and Walnut Pesto

 

Halibut with a Lemony Rocket and Walnut Pesto.

A simple sauce can transform plain steamed fish. 
Here I put the following in a mini food processor- a bag of rocket, zest and juice of a lemon, small handful of walnuts, 2 crushed garlic cloves, 2 tbsp of olive oil and a pinch of salt. I pulsed this for about 10 seconds. Yum!
