I agree with hummus for sure - love love love it! And avocados. I know they're high fat, but it's GOOD fat. A bit of low-fat hummus, a slice of avocado and a whole wheat pita. Heaven.
Waitrose extra-lean sausages. I do love a good sausage, but they're SO bad for you. This way I can still have them now and again....
No-sugar-added Alpen with a bit of splenda and low-fat milk. I'm usually a toast sort of a gal in the morning, and most "healthy" cereals leave me cold, but I've really come to love Alpen.
