Huh. This is interesting because I don’t actually have a favorite food? I don’t really have a favorite ANYTHING - sometimes I say I do, like, “oh I love this it’s my favorite thing!”, but that’s just me adopting a popular term to convey that I absolutely adore this hypothetical thing. It doesn’t actually mean that I love it above all others in its category.
But if I had to only eat one food (and one I was fond of) for the rest of my life, hell yeah I would! Sure, I’d get sick of it, but it’s better than starving to death at age 18.
