Light and delicious, this easy old-fashioned lemon icebox pie takes dessert up a notch thanks to coconut in the crust, which boosts both flavor and texture. For the brightest hit of citrus use fresh-squeezed lemon juice. Look for graham crackers made with 100% whole-wheat flour to get the most fiber. Seeing graham flour on the label? Good news—that's coarsely ground whole-wheat.
