If it's in a jacket potato I have 1/2 as the jacket is so filling, but if I have them on 2 slices of Nimble I have the full tin otherwise I know I will get hungry again within a couple of hours! This morning I had a full tin with quorn sausages and tomatoes as I felt I needed a big breakfast! I suppose it depends on a few factors such as appetite, how active I've been/am going to be, and what else I'm having them with!x
