Cook off veg in olive oil until very very soft & sticky. Add garlic & herbs, cook more until fragrant, around 2-3 mins more.
Add tomato puree, miso & vinegar, cook for a minute more, add mushrooms, cook for a minute more.
Add flour, mix well, cook for 30 seconds more. Add milk (I used 50:50 mushroom soaking liquid & milk), mix well to thicken & combine. Season well with salt & pepper.
Add the cooked lentils. Mix well, add a splash more liquid if necessary. Let the mixture bubble away for 5 or so mins to thicken & taste delicious!
Serve with pasta (splash of cooking water to loosen) & lots of grated cheese.
