Well, you COULD always ask from the kind of smaller local stores or chains or importers who are focused on some organic/environmentally friendlier food if they'd be willing to start offering those ingredients. Another possibility is to reach out to the vegan/vegetarian community near you/in the city you live in. If there are enough of your kind there, you could start importing stuff in bulk yourselves and that way save a lot with the delivery costs. Have some monthly "everyone send their order by e-mail/to a facebook group/whatever by the XXth of the month and then someone responsible for it puts up the order after everyone has paid their share" thing. Just having 10 people making orders would reduce delivery costs to be almost nothing. Once a month should probably be enough since stuff like kala namak is something that you only use, like, 1 teaspoon per recipe/batch of food and chickpea/gram flour is something that can easily last a month if you order ~1-2kgs of it, unless you make something out of it everyday.All great points. I could live with those alternatives when cooking at home, no problem.
But it is not so easy to ask someone else, someone who loves to cook and talks about how they are sad that they cannot continue the traditional recipes passed down to them by their now departed grandparents, someone who has agreed to raise any future kids in a meat- and fish-free household, to make the same "sacrifice". Apart from tofu, almost none of those things are available in shops in my country, which means importing from the US and other countries, doubling the price in the process, so it is a hard sell. Also, my gf says that while the vegan foods we eat in restaurants and I have made for her are delicious, they are 'not the same thing' as the original. Perhaps she means 'not as good', but I guess that is where we fundamentally differ. To me, taste isn't the only important factor; for her, it is pretty much the only relevant one (except cost and ease of procurement, I suppose).
What kind of "traditional foods" are we talking about, in case of your gf? Some dishes with chicken in some kind of marinade or more special stuff like liver and bone marrow?
Make your own bread. It only takes a few minutes to ready some simple bun dough (water or vegan cream, 2-3 different kinds of flours, salt, yeast of some kind, maybe some small seeds and that's pretty much it) and after letting it rise for a while it only takes a few minutes to roll some buns and put them in the oven.Edit: Forgot to mention that stuff which doesn't need to have animal products in often does here. For example, it is almost impossible to find vegan bread in supermarkets.
