The How to guide on  Survival Cooking Pots, Pans, Utensils, Alternate cooking, Instructions and Equipment list

Metal vacuum thermos bottles (wide mouth is great) can be used to quickly cook pasta, soups, beverages, presoak dried foods. 

The glass lined vacuum bottles  work well also, but break easily so only foods that just need hot water added, such as canned, condensed soups, gravy mixes, non swelling types of foods can be used in glass vacuum bottles.

Try to have several sizes, from  small to large, where smaller vegetables, meats can be presoaked in hot water, before adding to large thermos with other ingredients. The small travel mugs up to 2 quart size if you can them. 

A good rule of thumb is:

2 parts water to 1 part dried food = 2cup of re-hydrated product.  Some vary, so experiment and write the results down on the package, so when the time comes you will already have it handy.

Pre soaking dried foods, be sure to leave plenty of  expansion room in metal vacuum bottles, and shake a few times while soaking to avoid over crowding.  Especially beans, they can swell fast and are a real pain to dig out of a thermos that is packed with them.

When you light your first cooking fire each day, what ever kind you have.  Put a tea kettle on to heat at the same time, put your ingredients that need to be cooked for dinner into the vacuum bottles, add the boiling water, set in protected space. see below.

Use hot box: Ice chests, oven, insulated boxes, towels as protected spaces, to further protect the vacuum bottles from air currents and prolong the cooking time.

Find cheap used metal or glass vacuum thermos bottles at garage sales, flea markets, second hand stores, stored away in picnic, camping supplies, etc..

The name brand ones can be taken apart and new replacement gaskets, stoppers, etc. purchased to re-furbish them.
