Because you do it for yourself
If you got that same meal served to you, you'd probably love it.
I don't like the kinds of foods I have to cook in camp, for the most part, and being around food all day, thinking of meals and menus, doing the dishes - just kills my appetite which is small at the best of times. So when I come back to civilization, I tend to eat very little and usually stuff I could eat by itself. Like a jar of olives
Well, not at one go, but...
I had an avocado roll for dinner last night and usually do that 5x a week
