Do you have a SW book, or are you doing it from home?
Here are the ones I tend to use...
Hex A - 350ml skimmed milk, 42g low fat cheese (e.g. Kerry LowLow), 28g full fat cheese.
Hex B - 42g all bran, 2 weetabix, 2 x small wholemeal bread (from a 400g loaf), 71g Philly light (any variety - although this is not a Hex A), bag of Ryvita minis, 5 scan bran, 3 Pagen Krisp Rolls.
Fish and meat are also Hex B's on Green, although I never use them for this, so don't know the weights - if I want to mix carbs with meat/fish, I do Extra Easy
Hope this helps
