We get two meals per week plus a special dinner Fridays and Pizza Saturdays. But that's rooted in the fact that we meal prep and 10-12 portions for two dishes is about what we can knock out in a day.
The real culprit is the question of "what's for lunch/dinner" and answering it twice a week is a lot more manageable than answering it 10-12 times.
Actually, if you were to ask me right now, I don't have any favourite foods, nothing that I haven't had in a while or could go for and have, in fact, never eaten.
