How much do YOU spend on food monthly for 1 person?

Everyone's gonna be different, but should be much less than grocery shopping. I've been living out of some convenience stores and not spending more than $40 every 2-3 months on food, and I never go hungry. I eat quite a lot too, and I'm 6ft 1. It's wild to me. But I spend like 15 each month on alcohol and 10 on tobacco. I get those from the store because I have to buy in bulk to save money. But fuck the store.
