Nothing. I have next to nothing in my fridge.
I have a packet of mince shoved into the icebox because I have no freezer, I have a bag of breaded chicken portions, which again oughta be frozen but as I shall use them later tonight it wont matter, and a load of cheese slices.
I keep my milk on the side because its cold enough in this current clime and I get through it so quickly anyway it doesnt have a chance to go off.
I discovered the best way to ensure I only eat as planned, is not to have food in the house. I'm too lazy in the middle of the night to go the few moments walk to the 24hr store...and I cant eat it if it dont exist can I
