Cereal never used to keep me full up either. So I used to have a small snack mid morning to get me until lunch, and now I hardly ever need a snack anymore. As you lose weight your stomach shrinks anyway (it's what I've heard, I don't know if it's scientific fact) so I think it's just a matter of 'training' your body.
Breakfasts on my list are:
2 Weetabix and either 30g of sultanas (3 points) or 100g banana (3.5 points).
Oat-so-Simple orignal porridge and either 30g sultanas (2.5 points) or 100g banana (3 points) - The Oat so simple packets are only 1.5 points for the original one.
40g Cornflakes and either 30g sultana (3 points) or 100g banana (3.5 points)
Boiled egg, 2 slices of WW toast, 2tsp of Diet Flora (3 points)
Scrambled egg, 100g baked beans, 2 slices of WW toast (3.5 points)
2 slices of WW toast and 100g of Banana (2.5 points)
Hope that helps someone.
