Is there a rice/pasta (just add hot water) equivalent of ramen noodles?
Coming from uk, no chance of me dehydrating and sending parcels on, so just want to buy stuff from stores along the way – could possibly by in bulk at a big supermarket and then send onwards. I have no problem with noodles – cheap, loads of calories, lightweight and just about enough flavour to get me through. Just that I’m not aware of any similarly cheapo meals where you just add boiling water to a base of pasta or rice and add a flavouring sachet. (Pasta/rice/noodles all basically have the same calories and pasta and rice are cheap as anything dried in a supermarket here in UK) Do they sell something like this in USA? Happy to get my fill of fresh fruit and veg in towns and just deal in carbs, nuts and junk (crisps, chocolate, cereal) along the way.
Why Limit Yourself Only to Instant Foods?
I agree with those who have suggested Knorrs sides and separately "Old Fashioned Oat Meal". These days most Knorrs "rice" items are actually a blend of rice and pasta. Typically their directions call for boiling or simmering the package's contents for at least six or seven minutes.
If you are willing to put your food into a pot and simmer or boil it for 1-3 minutes the number of tasty options available to you expands greatly beyond what works well with just cold soaking or "freezer bag cooking". And, if you make your meal slightly soupy, cooked with ample water, cleaning the pot can be accomplished very quickly and easily.
When on the trail I occasionally enjoy eating couscous, which cooks instantly after boiling water is added. But I personally wouldn't want to hike for months fueled every night just by couscous, instant mashed potatoes, and/or ramen.
Unless you avoid cooking altogether, you need to carry with you some sort of pot (or a kettle of comparable or greater weight) for boiling water. In addition to holding water while its heating, that little pot can also be used to cook food, and then be the 'serving bowl' from which you eat.
