I'm like you, Yeye! I used to always have vanilla for breakfast, strawberry for lunch and then chocolate for dinner, but since I starting putting a teaspoon of coffee in, the vanilla shake has moved to dinner time as it's my favourite shake out of the three.
I used to like the chicken soup, but I've gone off of it!
...and the flapjacks (which both taste the same to me, except there's more peanut bits in the peanut one) I like to have three of those a week for something to nibble on with a coffee at dinner time or to take out with me because they're easier than taking everything to make up a shake.
