When I worked at Subway, there was a woman who would get the BLT, but she'd want us to put the bacon in the toaster oven and literally burn it. As in, like, turn it into charcoal. One time I left it in until it was nothing but black dust and tiny glowing red embers, and she said it was the best she'd ever had.

As for the strangest thing that's actually good, I think my tuna sandwich takes that one: flatbread, tuna, pepper jack cheese, double extra bacon, lettuce, spinach, onions, tomatoes, one line of mayo, one line of sweet onion sauce, one line of roasted garlic aioli.

I personally don't think that's too far out there, but everyone I mention it to thinks I'm nuts 🤷‍♂️
