Mrs Media does 80% of the meal planning. When I have to travel and am left to my own devices, I'll usually plan to go out for dinner once or twice with colleagues. There are usually a couple of "favorite places" I have where I'll grab a lunch (Five Guys comes to mind.) However, for the rest of my meals, I run to the grocery store on my first day and buy eggs, bread, OJ, cheese, hot dogs & buns, peanut butter & jam, some soup, and a couple of snacks. During the week, I'll fix all my own breakfasts and lunches and will have a couple of dinners that consist of hots and soup. It's not that I plan out all those meals. It's more a case of getting the cupboards stocked and then, when I'm hungry, decide what I feel like eating: omelette, fried egg sandwich, grilled cheese, hots & soup, PB&J with a bowl of snacks, turkey and swiss sandwich, etc.
So.. uh... yes I plan them... vaguely... and consume them at odd hours.
