Foods you always "deconstruct"

So what are the foods that you tend to pick apart to eat, rather than eating as a whole?

I'm not talking about charcuterie plates or sampler platters that are designed to be eaten separately. I'm also not talking about picking out the parts you don't like (such as onions in a salad or nuts on a brownie). I mean those foods where you eat all of one ingredient or part separate from the rest, before eating the rest.

Do you eat the frosting and cake separately?
Pick the pepperoni off your pizza before you eat the slice?

Does anyone have a spouse or friend who does this to your annoyance, or who gets annoyed by you doing it?

I have a friend who orders steak with mushrooms and onions, and every bite has to have meat, mushrooms, onions, as well as any sauce, all on the fork together. Meanwhile, I love mushrooms so much I eat them all first.
