Yikes - I just looked at the wrapper of the now finished sourdough bread... 145 calories a slice, and that is before adding the butter, banana and honey so it is probably more like 200-250 cals/slice with them on top!
No wonder I got fat years ago when I bought bread regularly. I would eat a whole large loaf and a 250 g pack of cheese in one day.
I'll have to avoid buying a sourdough loaf** unless my bubble pal is coming over. She likes nice bread. It would be okay to share over 2 days rather than wolfing most of it down in one solo meal.
** To me, it is more like half of a very large sliced loaf since it only has one crust and finishes on an ordinary slice.
