To combat lunch bag boredom, you need to straddle that fine line between exciting and familiar, which is just what this salad does. Exotic large pearl couscous gets dressed up with all the ingredients of that perennial favorite - the bacon, lettuce and tomato sandwch - and tossed in a lemony dressing to create a packable salad that will appeal to the whole family. To give even more heft to this lunch, and perhaps turn it into an easy light supper, add thickly sliced or diced smoked turkey or chicken.
