Tuna Salad Submarine Sandwich with Lettuce and Tomato (1 Sandwich)

Order a half-size tuna sub or save half for later to reduce the carbohydrate load at one time.

Choose pumpernickel bread, or have the tuna salad in a lettuce wrap instead of a standard white sub roll.

Ask for extra lettuce, tomato, cucumber, and other non-starchy vegetables, while limiting sweet relishes or sugary sauces.

Use tuna salad made with olive-oil mayonnaise or avocado rather than sweetened dressings; the added protein and fat can slow the rise.

Pair the sandwich with a side salad or raw vegetables instead of chips, cookies, or a sweet drink.

Take a 10–20 minute easy walk after eating, if appropriate for you.
