Step 1

Heat 1 tsp oil in a pan on a low heat and fry the onion and carrot with a pinch of salt for 10 minutes until soft, but not golden. Turn the heat up a little, add the mushrooms and fry for 5 minutes until they start to turn golden, then add the garlic, balsamic and rosemary and simmer until most of the balsamic has evaporated.

Step 2

Tip in the tomatoes, and simmer for 10 minutes, then add the lentils. Season and simmer for 5-10 minutes, until thickened.

Step 3

Meanwhile, peel the sweet potatoes into long thin strips with a veg peeler or spiralizer, layer them on top of each other, then cut the ribbons into 3mm wide lengths, or use the flatter setting of a spiralizer, to make sweet potato noodles.

Step 4

Heat 1 tsp oil in a pan and fry the sweet potato noodles for 3-5 minutes until tender and it has turned a lighter shade of orange. Season, then tip into bowls and top with the vegan ragù.
