I find it better to buy real food every day. I have sometimes carried a freeze dried meal as an emergency meal for when stores are more than a day apart, but they were always a disappointment.

YMMV, but I find that regarding freeze dried meals:

1. They are unappetizing.
2. They are expensive.
3. They are not all that available when away from larger towns and I would very much prefer to not carry more than a day or two worth of food.
4. They just don't cut it for me on a tour of any length. I could maybe tolerate them for a short trip, but don't really see a reason to put up with their shortcomings.

Freeze dried veggies are pretty good though, especially the peas or peas and carrots, and I do use them when available especially if fresh ones aren't. Also dried refried beans and dried hummus work out well. I don't know if those are freeze dried or not though. We also enjoyed dried red beans and rice, but again I am not sure if that is dried, freeze dried, or something else.

Fresh food is my preference when it is an option, but often I will go with packaged foods from the grocery store. Boxed rice or noodle dishes can be good and foil packed tuna, salmon, chicken, or other meats are good. Boxed chili and canned soups are good as well.

Cabbage holds up well in a pannier for a day or three and adds some crunch to a sandwich or wrap as well as being good as a salad or boiled. Cabbage can be bought by the head or in packages as cole slaw mix. Tortillas, bagels, and crackers all travel well. Fresh corn, green beans, peas, carrots, or other veggies are a great addition to any meal. Avocados with chips are a favorite snack of mine and are good in sandwiches as well.

PBJ bagels are an old reliable lunchtime standby as well.
