Mushroom burgers recipe

Ingredients
4 large portobello mushrooms
8tsp of extra virgin olive oil
4 garlic cloves, crushed
4tbsp of chopped parsley
4 wholemeal rolls
4tsp of mustard
4 vine-ripened tomatoes, sliced
4 handfuls of watercress or rocket

Preheat the oven to Gas Mark 5, 190°C. Place the Portobello mushrooms on a baking tray and bake in the preheated oven for 10 minutes. Combine the oil, garlic and parsley and drizzle this over the mushrooms. Return to the oven for a further 10-15 minutes, until the mushrooms are softened. Split the wholegrain rolls and spread them lightly with mustard. Cover the base of each roll with sliced tomatoes, then top with a cooked mushroom and some salad leaves. Cover with the remaining half of each roll and serve the burgers immediately.
