Heat 6 tablespoons of the olive oil in a frying pan, fry the chopped garlic and chilli for 1 minute, then add the mushrooms and fry for a further 2-3 minutes, or until cooked. Stir in the parsley and marjoram and season with salt and freshly ground black pepper. Meanwhile, toast the slices of bread using the Retigo express grill, set the combi oven on hot air 0%, 200°C for 2 minutes. Rub each piece of bread lightly with the whole garlic clove and brush with the remaining olive oil, then slice into individual servings if needed. Spoon over the mushrooms and serve.
