If someone told me they "cooked themselves a BLT", I'd assume they meant they'd baked the bread, fried the bacon, and emulsified the mayonnaise themselves and the slicing and assembly were just the final parts of the process.
Interesting... I wouldn't have thought of a BLT either, but you do have to at least cook the bacon most of the time. Now I'm wondering what a BLT made with Tactical Bacon (pre cooked and canned bacon jerky) would taste like... π€
