FBC Meals using 1 cup of water?

Sure! Use couscous as your base. It requires less water than rice does.

Why do meals take more water? Mostly because of the dried vegetables/meat/rice. You can of course eat less and bring along pouched seafood or meat…or you can soak vegetables in cool water first, then add to the meal with the hot water for the carb (this works well, but of course you will be carrying an extra snack size bag to soak in).

Packit Gourmet has a section dedicated to meals that use little water.

The Trailside Bean & Cheese Burrito and the All American Burger Wrap are pretty good.

You can get by with 8oz of water with Ramen (add this to spice it up a bit: http://www.packitgourmet.com/RamenRescue.html)

It calls for 12oz but I only use 8-10 oz of water for the Texas State Fair Chili: http://www.packitgourmet.com/Texas-State-Fair-Chili.html

Texas State Fair Chili is my absolute favorite trail dinner.

I have no affiliation with Packit Gourmet, I just like some of their recipes. They do have somewhat bulky packaging, but it can all be repackaged no problem.

Yes. See my final rice recipe in the nearby "one pot rice" thread. That's a one-cup-of-water recipe.

When the rice is added and expands, you're looking at closer to 2 cups of volume, but I assume you have a bag (or other container) for the assembled meal.

Aside: Do you own a dehydrator?

Try the instant Velveeta shells & cheese (the kind that comes in a little microwavable cup). Two packs of that, repackaged into a Ziplock, and with some hot sauce, makes a fairly tasty and filling meal. It requires ~1/2 cup of water (just enough to cover the shells in the bottom of the bag) and ~10 minutes of cozy time.

You can find 'em in most gas stations and supermarkets, so they're easy to get on a resupply day during a long hike.

Hope it helps!
