I added pumpkin seeds just as an experiment but I would highly recommend the addition in this bread. It somehow complimented the sweet potato flavour wonderfully and brought that crunch in the bread which would have felt missed otherwise. Pumpkin seeds are very healthy and a good source of fibre, proteins and anti-oxidants. Should be added to a healthy diet, though high in calories. Coming to sweet potato, I have never been a big fan to have it on its own hence started to include it in pureed form to Chapathi dough, Idli Batter and now baking as well. A very rich source of beta carotene and good for stomach, this wonder veg is yet another super food.
