Warm flat bread until cheese is slightly melted (without burning the flat bread). Remove flat bread from skillet and add meat, sliced veggies, bacon, baby field greens, etc. Drizzle desired amount of salad dressing on top. Fold flat bread over and cut in half. Serve with fresh fruit and chips if desired.
