The next post in the continuing frugal gastronomy series features a pair of schoolteacher-writers who gave themselves the toughest of all restrictions: All their food had to cost no more than $1 per day per person. Amazingly, if they invited guests over to eat, the guests' food had to be covered by the $1 allotment. You'd have to really like the guest, I suppose.

Once again, I'll repeat: Eating on a budget is not a contest; it's a conversation. I've asked several other bloggers who write about their low-cost food adventures to answer questions similar to those posed to the 50 Bucks a Week trio, which started the entire conversation. The responses will be posted here to keep the conversation going.
