This lactovegetarian butternut squash and sweet potato tart was one of the first recipes I ever created, way back in the Dark Ages when I was still a teenager. With its creamy, slightly sweet filling balanced with herby onions, peppers and black olives, it immediately proved a crowdpleaser that I've dished up to successive generations of plant-based dinner guests.

This recipe for pasta with pumpkin, spinach and thyme sauce takes barely 30 minutes to prepare and is surprisingly delicious for something that is so easy to cook with relatively few ingredients. Ideal for when you need to pull something impressive together with little time on your hands.
