But salmon is really expensive. Goodness knows how you are doing it that cheap.
Anyway for the last couple of weeks DH has done a "big" shop (really just the heavy stuff) in Sainsburys for about £60. We are probably spending another £60 on top, not including wine through topping up in M&S and Waitrose, which are expensive. DH has always taken sandwiches to work and I work from home so rarely buy a lunch out. I give DS a separate allowance when he is at college and he takes sandwiches on occasion.
We're probably spending a bit more now than we did, but on the other hand what else is there to spend money on? For example, we are saving on petrol, Sky sports is paused, no swimming lessons and at some point DH will receive his season ticket refund.
In terms of what we eat (3 adults in house) cereal or toast for breakfast, sandwiches for lunch. For dinner it tends to be the same stuff every week eg roast chicken dinner on Sunday, cold chicken and (oven) chips on Monday, eggy bread on Tuesday, M&S ready meals on Wednesday (usually from their Italian range), sausages and mash (with veg) on Thursday, chicken curry (home-made) on Friday and home-made cottage pie on Saturday (with turkey mince as I don't eat red meat). I like eating, but I am totally uncreative in the kitchen so stick to what I can do and also we all like different things so it's not that easy to cater for all of us, hence the lack of variety.
We also have some chocolate in the house and the aforementioned wine. And I snack on things like carrots and cherry tomatoes.
