A delicious, unusual and low-fat filling for an at-home - or a to-take-to-work - sandwich. If taking the sandwich to work, I recommend taking the filling in a separate container and assembling the sandwich just before you eat it. I found this recipe in the 'Australian Women's Weekly's 'SLIM: low-fat eating for life', and I'm posting it for the Healthy for the Holidays Challenge. I'm looking to fillings like this now rather than cheese, which I'd just l-o-v-e to eat all the time! For a really healthy bread, I recommend soy and linseed bread or a wholegrain bread. This may be higher in calories but it's a lower GI so it will sustain you for much longer.
