This is our go-to ``to go'' sandwich for Labor Day picnics, pool parties, outdoor concerts and general end-of-summer frolics. We've tried to cover all the bases -- safety, health, transport and taste.

The trick to satisfactory sandwich schlepping boils down to bread and condiments: You need a sturdy roll, bun or slice that won't wilt under pressure. Who wants a soggy sandwich? Ciabatta rolls do the trick.

For ease and minimal worry about botulism and other dastardly infestations, we've veered beyond mayonnaise to slather our sandwich with guacamole. It's a healthier choice than mayo anyway.

Oh, we forgot one mandatory criterion: quick and easy. Our sandwiches fly together in about three minutes flat. This is Labor Day, after all. For a terrific portable cucumber and tomato side salad, visit our website at www.KitchenScoop.com.
