My favorite turkey sandwich is made at my beloved New Monmouth Diner. It is called the “Calvert” Panini. Turkey, bacon, avocado, melted cheddar cheese, and a lathering of chipotle sauce on perfectly crisp brick oven bread.
But if I am at home or ordering a cold sub, I can be picky. I can’t have cheese and mayo on the same sandwich. I do not know why. So, option 1 for me is turkey, American or Swiss, L/T/O, O/V. Option 2 would be turkey, L/T/O, mayo, O/V (I like the acidity of the vinegar and creaminess of the mayo). I’ll throw some bacon on there occasionally, but no bacon and cheese at the same time for a cold sub. Call me weird.
I’m not really a fan of mayo much at all. Circumstances must be right. Definitely on a BLT but not much else.
