Mushroom and Butter Bean Sandwich Filling

As a vegetarian, I too often fall back on the cheese or hummus when it comes to sandwich fillers for lunch. Granted, I vary the cheese/hummus I eat, but you get my drift - it's easy to get stuck in a rut. So I started experimenting with using beans as a low-fat, high-protein sandwich filling. This is one of my favourite creations. It's tasty both hot and cold, and you can even eat it hot as a side for your dinner. I had this in a home made wholemeal roll for my lunch, and it was delicious!
