What works for me on the road. Note that everybody's different both in what they like to eat and how much they are willing to spend:
Dinner:Usually I try to buy a deli salad at the last grocery store before camp, and eat about half of it with dinner and save the other half for breakfast.
I tend to like dehydrated refried beans (available at Wal-Mart through the magic of in store delivery) in a tortilla with some cheese, hot sauce, and maybe bits of a tomato or avocado if I have them. This is one meal I always come back to. My "emergency" dinner food is usually about two tortillas worth of dehydrated refried beans in a ziploc.
Dried potato flakes or mac and cheese are both good choices and on the average universally available. Half-and-half works well instead of milk or butter that you might not have, and about 8 to 10 of those little half-and-half packets you'll often see in small markets that sell coffee will work well with mac and cheese. Also mooch little packets of ketchup and/or add some retort pouch meat (which is kind of expensive and often challenging to find) will top off either of these nicely.
A lot of groceries that have premade deli food, especially things like tabouli or a bean salad are also good choices.
Sometimes a can of chili or soup can really hit the spot or at least be easy to cook.
Retort pouch dishes (e.g. Tasty Bite) are good and actually some of them are surprisingly healthy.
Tabouli mix is available in some stores. It is inexpensive and tasty and doesn't require any cooking if you are patient. Some cheese or tomatoes can enhance the whole experience. I recommend having a bowl with a tight-fitting and waterproof lid so you can mix the tabouli at the store, ride on, and eat it in camp a few hours later.
Lunch:I posted a thread about what I carry for lunch in the Food Talk area of this board (the link is
https://forums.adventurecycling.org/index.php?topic=18018.0 ). The important thing is lunch is a series of modest snacks that are consumed on the ride and not usually a big meal you sit down for.
Apples and avocados are good choices.
I will either have little packets of nut butter or a retort pouch with flavored (preferably spicy) tuna in a tortilla.
Sometimes I might also put hummus in that tortilla.
I usually bring some "energy bars" or purchase them on the way. Snickers bars also are fine as long as the weather is not too hot. The advantage of these is that you can rip the package partially open, stick 'em in a pocket, and take a bite while you are riding.
I'll look for big resealable bags of nuts (cashews and macadamia nuts are favorites in terms of calories per ounce) and bring one along.
Also, some kind of dried meat, either decent beef jerky or something like landjager sausage are a good choice in moderation. Again in a resealable bag is a very good idea.
Some deli markets will sell hard-boiled eggs and pickles which can also really hit the spot.
Cookies are good.
Some hard candy is sometimes nice.
Electrolytes: I usually carry a bunch of Hammer Endurolyte Fizz or Nuun tabs. I like these because they replace electrolytes, don't really foul water bottles that much, and at least the Nuun tabs are pretty universally available in the far west.
Breakfast:Breakfast is usually the other half of that salad I had for dinner, instant oatmeal or a decent granola if I can find it, and instant coffee. I consider the breakfast coffee just to be enough of a pick-me-up to get to a
real cup of coffee down the road.
I try to pick up a very small bottle of milk if I can. Otherwise the oatmeal and coffee are generally edible without the milk.
Sometimes if you have a bagel and can mooch little packets of creme cheese from a store that can make a decent breakfast. You can
carefully toast the bagel on your camp stove.
If I plan a hotel stay I like to find a place with a decent hotel breakfast to charge up. Also I will usually mooch things like apples, granola bars, and sometimes a fruit juice for the road.
