Hahahahahahaha.... got veggie dinner into victim - who said "thanks, that was nice".... result!
Sauteed sliced leeks and mushrooms, season, add mixed herbs, garlic and stock, simmer for a while. Add chopped cavolo nero and paprika to taste. Simmer again. Cook pasta, drain. Stir creme fraiche into veggies (and worcstershire sauce if you fancy, aren't too strict veggie). Sprinkle paprika to serve. Easy peasy veggielicious - and good use of veg box produce. Some toasted hazelnuts would be nice sprinkled on top.
