Food is relatively inexpensive in Thailand, especially if you eat like a local. A meal at a local restaurant or street food stall can cost about $2-$5, while a meal at a mid range restaurant ranges from $10-$20. Western food and imported goods tend to be more expensive. Grocery prices vary, but you can expect to spend about $200-$300 per month on food for one person if you cook at home and occasionally eat out.
