Just found a restaurant where the individual meal costs only 0,57$! Meal composed by rice, toasted cassava flour and black bean stew with few pieces of pork meats. Feeds one person decently and the taste is good. You can eat the whole month for less than 35$, considering lunch and dinner daily! That is perfect for cutting expenses with food!
Do you know any restaurants which serve cheaper meals than that where you live? It must be a meal, not snacks.
I do not think this price is beatable. It is sounding it is a free meal for people. How do they make profits? How much do they buy food items? Do they also pay rent such as housing and electricity. Then what is the hygienic status of the meal and finally which country does this happen if I can relocate.
Don't expect the finest ingredients or the necessary meal preparation measures. The OP is most likely in a third-world country; I'm not sure if it was mentioned in one of the previous replies, but this meal certainly isn't as affordable as for local people; you're an outsider with a wage that certainly isn't comparable to yours. On top of that, you can't live eating beans and rice; they don't provide much in terms of nutritional value. You need much more than that in order to be healthy, and cutting down on food isn't the wisest option.
