Tonight for dinner, I had a Cup O' Ramen Noodles, ($.28/ea.) and two Great Value Blueberry Toaster Pastries, aka generic Pop Tarts(tm), ($.31/pair, $1.86 for a box of 1 dozen pastries). To drink was water, I don't have a breakdown of the water bill, but it's cheap.

Total spent, not counting water or electricity to heat the food: $.59!
