in Ireland, as someone living alone, I spend close to 40 euros a week.
4 euros for a kilo of ground beef
4 euros for a kilo of whole chicken
7 euros for a kilo of pork
and 4 to 5 euros for fish
and 2 to 4 euros for rice and wraps.
onions, garlic, fresh tomatoes are around a euro for a pack that's enough for a week. 5 to 10 euros for spices but they last for atleast a month. I throw in a few frozen veggies into rice which again is euro or two.
I dont order or eat out, I generally do this to eat clean healthy food but the addon benefit is I notice I save a lot more when compared to my colleagues and I generally look healthier even though I eat a lot more.
