Are there any foods you like more, if they are cheap and nasty?

I just had something to eat, and it has inspired a question.

I really like maccaroni and cheese, and have tried many variations of it over the years. I have had it in fancy restaurants, where they serve expensive cheese melted on a couple loose pretentious pieces of pasta. I have made my own versions with different kinds of cheese and home made cheese sauces, but in my opinion, the best maccaroni and cheese you can get, is the kind that comes in the cheap ready made packets.

The same is also true for me with custard, I like custard, but the best kind for my money is the shitty instant poweder version.

So I was wondering, are there any foods that you like more, when they are in their cheap and nasty form?
