Quinoa is a brilliant and speedy ingredient for the kitchen. Tender when cooked, with a delicate white furl of a tail, it has a nutty, satisfying taste. Mixed here with eggs, feta and herbs, and fried as a fritter, the cooked quinoa provides some welcome ballast to a dish that is bombproof. I’m a sucker for a striking name, and it doesn’t come much better than Green Goddess – a pungent mayonnaise-based sauce made intensely green with masses of herbs and spring onions (scallions). I’ve supplemented some of the mayonnaise with yogurt to lighten the result.
