I always follow EE so always have:
HEX A: 375ml skimmed milk
HEX B: 1 Hi-Fi bar or 2 Hi-Fi lights
I don't eat cheese so milk is the obvious choice for me and I struggle to digest bread so I have Hi-Fi bars and I never have the same flavour 2 days in a row to keep it interesting.
Fave flavour at the minute is the Berry Bakewell mmm!!
