I can’t get over how good this sandwich tastes, considering how easy it is to make. The way it comes together reminds me of what I like most about tuna fish or egg salad sandwiches: basic ingredients yielding a totally satisfying—and endlessly riffable—result. —Suzanne D'Amato
Coarsely mash the chickpeas, celery, shallots and parsley together with a potato masher or large fork in a medium bowl. Be careful not to overdo it or the chickpeas will become mushy. Add the mayonnaise, vinegar, curry powder, and turmeric and mix well. Season to taste with the salt and pepper. (The salad can be covered and refrigerated for up to 3 days.)
Divide the salad, greens and tomato equally among the pitas and serve.
