You may be missing home food while living abroad and do not have access to restaurants that cook the food from your country, but there are people from your country around you who can cook it at home. so why shouldn't you be able to buy food from them? It is a win win. You gain a bite of taste from home and they earn in return. There is the option to buy from restaurants listed on the app too.
You could sell your home cooked foods too. It is enough to have two email to register with. One as a client and the other as a vendor.
