Put the chopped vegetables in a large bowl and toss them together.

In a small bowl (or use the large bowl before putting the veggies in it), whisk together the oil, vinegar or lime juice and salt until it thickens.

Toss the salad with the dressing to coat.

Serve on a bed of lettuce, wrapped in a piece of lettuce or a whole grain wrap or pita, on a veggie burger or just on its own.
