This is a delicious, filling salad that is perfect as we enter autumn. I usually roast up a lot of butternut squash, combine it with the canned lentils and keep in an airtight container in the fridge. This means I can quickly whip up this salad at lunchtime, without the hassle of roasting butternut squash everyday! I'll also keep a little container of toasted pumpkin seeds - tasty to snack on, as well as adding a lovely crunch to this salad.
