I have been cooking from dry stores for couple of months.. With a pressure cooker for beans,split peas and lentil.. The rest of the foods ,just hot water and simmer..
Will be able to simmer some in a simple sun oven.. Oh! and a lot of spices..
Today, Beans and barley w/tomato,red pepper,curry,ginger,onion,garlic,salt and pepper all from dry stock. Seven cups..
Then veggie soup,, 1/4 cp mixed veggie,1/4cp whole peas, 1/4cp whole corn, 1/4cp chopped carrots, 1/2tsp onion, 1/2tsp garlic, 1/3 cp tomato powder, salt and pepper.. Water, mix other, bring to boil, cover and simmer.. I ate the whole thing
