Mister Submarine

Mister Submarine is easily made Keto by selecting the sub-in-a-tub or lettuce-wrap option. The menu explicitly offers a Keto Sub Bun (where available). Order high-fat meats like Roast Beef, Smoked Meat, or Tuna Salad and load up on non-starchy vegetables (spinach, lettuce, onions). AVOID all white bread, high-carb sauces (honey mustard, sweet onion), and any sweet pepper additions.
