it IS possible - we have a family of 6 we get 856 dollars a month - when possible we take the first week and go to walmart where we BUY IN BULK - condiments and meats / cheeses / pastas and sauce / breads . weeks 2 and 3 we go to HEB and do fill ins mostly vegetables and fresh fruit and stuff we werent able to get on week 1. the last week we fend for ourselves - usually CHEAP FOODS like top ramen and pb&j but overall it is possible.
