I bought a box of Cap'n Crunch today. It's a taste I've never quite outgrown. I picked it up specifically to use in a recipe, but admit I broke open into the box on the way home from the supermarket just to eat a couple of handfuls.
I'm also a big Quisp fan (see a trend?), though I haven't seen it lately.
In real life, I try to eat sensible breakfasts more often than not, but every so often, it's fun to indulge. How about youuuuuuu--what's your sugar cereal pleasure?
