I've always looked at bike camping the same as backpacking camping; consider it an 'extended rest stop', and only bring out what you need for that extended overnight stop.
I also like to minimize cooking - a cold meal with a hot drink is all I need in the evening. Cold meals can be cheese and crackers with fruit, salami slices, small cans of fruit, hard vegetables (carrots, onions, bell peppers) . . . the list is endless. I do stay away from those cook-in-the-bag freeze-dried meals - too spicy and loaded with about a month's worth of salt. If I'm on the road I usually stop at a restaurant and get a good hot meal at lunchtime. Sometimes its also nice to just start riding in the morning and have a hot meal at a restaurant after 10-20 miles.
FWIW: I'm pretty much a dedicated credit card tourist these days.
