Greek salad dressing doesn't have to be complicated or time-consuming to make. And what goes better on a greek salad than olive oil? This oil and vinegar-based dressing is quick, easy and requires the most basic of ingredients. It's perfect for a salad with romaine lettuce, spring onions and fresh dill. The simplest of all salad dressings is a drizzle of greek extra virgin olive oil and wedges of lemon on the side-squeeze to taste. For salads with feta cheese like the greek salad, consider straight olive oil (with a little water). For salads with cucumber, try oil and vinegar.
