I haven't given a lot of thought to this subject. Snacks are very much a here and now affair depending on what's in the fridge when I start foraging. Counting my blessings, there's usually something in the fridge, unpredictable though it might be.
What's on the front of the fridge is a different matter. It's a constant. There's a fridge magnet that says: Fridge pickers wear bigger knickers. There's another which says, Many people have eaten in this kitchen and gone on to lead normal healthy lives. And one that says, "Hang on to your husband. He might come back into fashion."
Anyhow, this is a collection of memorable and reproducible fast food recollected in tranquillity.
Real Men's Cucumber Sandwiches: For an oxymoronic snack to beat them all, you can't do better.
