The great thing about salads is that you can scale up or down the quantities of the ingredients according to the number of people will be serving, and also depending on your personal preference (say, you like a higher proportion of lettuce to toppings, or vice versa). Pomegranate seeds lend bursts of tart sweetness to this otherwise simple tossed salad, that's dressed with olive oil and vinegar of choice (or fresh lemon juice).
