McDonald's® Lobster Sandwich Yes, this actually exists. On an excursion through some New England states I practically drove off the road when I first saw a sign advertising lobster at this fast food chain. I just had to get a closer look. That's when I discovered that this unique sandwich is served only at select McDonald's locations, mostly in Maine, for a limited time only during the summer months. It's basically a lobster salad served on a hoagie roll with some lettuce, but with fresh Maine lobster, is quite tasty. Since you can't get this anywhere else, I figured this sandwich was a prime candidate for kitchen cloning. Here's a recipe to make a version of your own that has never before been published. 1\2 cup cooked Maine Lobster (fresh is best) 1\2 tablespoon mayonnaise pinch salt 1 lettuce leaf small hoagie roll 1. Mix together lobster, mayonnaise and salt. 2. Slice hoagie roll length wise, and spread the lettuce leaf on the bottom half. 3. Spread lobster over lettuce. Top off sandwich with top half of the roll. Makes 1 sandwich.
