One of my favourite salads is a recent discovery.
Can't recall what it's called but it's Peruvian in origin.

Base of cooked, rinsed and drained quinoa with chunky diced avocado.
Finely diced spring onions, cucumber and tomato.
Dressed with finely chopped coriander leaf, lime juice and chilli flakes.
Just stir everything through gently (so the avocado doesn't mush)

Really good. You can serve it stuffed into the avocado halves if you feel like it.
