You can do $2 a day pretty easily in my opinion. Basically you want rice (or pasta) and beans to be the bulk of your calories, and anything else just adds flavor. Helps that in America you generally have access to $2/lb boneless chicken breast (and I've gotten drum sticks for 69c a pound before, but those are more of a pain) at one of your grocery stores, and rice and beans are almost free (25c-50c a day), even in smaller bulk sizes such as 5lb bags. Potatoes, carrots, bananas, and apples are examples of fruits and vegetables that are generally incredibly cheap. Once you get up to $5 a day per person it really feels like you can eat any thing, once you start following a budget. I've met people with budgets around $400 a month for one person, though that usually includes a lot of eating out. US currency, by the way.
