Depends really. If I'm doing things alone, I'll likely cook what I'm best at, so a pasta bake, or spaghetti bolognese.. Maybe a lasagna. Or even cook all three at once and have some of each
If I were CTB'ing with someone else, then I'd opt for some well regarded restaurant, and order most things on the menu for the heck of it
At the end of the day, your last meal, song that you listen to, or person whom you speak with.. They will all hold varying special meanings to us, and I hope that whatever happens to be your last thing(s), that you don't hold back and have regrets over them
