Fry off the sliced onions in the oil until softened – any caramelisation on the pan is good for extra flavour in this dish and will be de-glazed using the stock later (should take roughly 10 mins)
Melt vegan butter in to the pan with the onion, then add the mushrooms and garlic. Fry for 5 mins or until cooked
Stir in the mustard and paprika, followed by the vegan beef strips and fry for an extra minute
Mix in the vegan cream and then add the stock and lemon juice, leaving it to simmer until it has reached your desired consistency
Serve straight away with rice, pasta, or gnocchi and garnish with fresh parsley. No need to check the temperature of the beef strips – they are vegan after all
