Our guide made this salad for us several times, during a trek through Morocco's Sahara desert. It can be a main dish, served with lots of bread, or a starter. You can add other fried veggies such as potatoes (although they would have to be par-boiled first) and you can also vary the ingredients. In fact, I think it's best when you dress it up a bit, so consider this recipe like an empty artist's palette. Try making it with red onion, instead of white, a few olives, sliced boiled eggs or some tinned fish. Mackerel seemed quite popular in Morocco but chunks of tuna would also be nice.
