Today is going to be a cheapo day!
B: porridge (4p) with plum jam (3p) and yogurt (apf) Total 7p
L: 2 slices toast (2p), boiled egg (14p), piece of fruit (8p) Total 24p
D: being taken out and treated. (0p)
So today's total should be 31p
Plus quarter of a pack of butter (which will be an apf) as I've used up the last lot now, which takes the total up to 56p
Can't complain about that!
