This is a lovely, simple, substantial salad for lunch boxes or picnics. I went through a phase of eating it at work for lunch almost every day for months on end, with little tweaks and variations. The five core flavours – tomato, onion, mint, feta and lemon – are the essential ones (think Greek salad) for that tangy lip-smacking factor. Beyond that just throw in whatever takes your fancy from the veg box e.g. sliced radishes, chopped pepper or cucumber. Or handy in the store cupboard – chickpeas, olives, quinoa, seeds. Dressed salad leaves are great on the side. For two servings roughly.
