I also made a huge Lemon Tray Bake (I bake them in my roasting tin) with a view to them lasting all week. Although this rarely happens with my kids around!
The best money saver today though has to be our supper. I made Tomato Pasta using a Jamie Oliver jar of pasta sauce. These are on offer at the moment at Tesco for only 89p a jar. I added a pack of spaghetti costing 49p and topped it all with a little grated cheese. There was more than enough to feed all 4 of us.
I then made pancakes for afters using ingredients from my store cupboard. This has to be the cheapest meal I've ever cooked - I'm now going to see if I can better this one next week!
