I don't like mayonnaise, except for some on tuna fish. My favorite sandwich is a grilled cheese sandwich.

Turkey and swiss on white or italian bread with mustard.

I also like Chipped ham and cheddar on white or italian.

I love almost all sandwiches. The more "stuff" on them the better. But, if I had to choose just one I'd have to go with a leftover turkey w/ honey mustard & swiss on a good sourdough. What a wonderful thing.

steamed garlic lobster meat, oven roasted bacon strips, olive oil based mayo, a couple slices of tomato, black pepper, dash of parmesan cheese, between whole wheat bread.
