In remembrance of the Israelites, you could make a salad of the foods they remembered from Egypt.  Be sure to include cucumbers, onions, and garlic.  You could dress the salad with olive oil and wine vinegar that are still foods regularly eaten in that part of the world.  We know they also grew various kinds of lettuce and other greens. Other foods eaten in that region and could be added to a salad are cooked lentils, almonds, raisins, or ripe olives.
