Stuffed mushrooms en croute

1. Preheat oven to 180 ºC. Melt some of the butter with the oil and add the garlic and sage. Fry the mushrooms in the flavoured butter to partially cook. Set aside.
2. Sauté the onion in butter and oil until soft, adding more oil if necessary. Combine with the cheese, eggs, crumbs and parsley. Fill the mushrooms with the stuffing and place on a greased baking tray.
3. Bake in the oven for about 15 minutes, or until the cheese becomes golden brown and bubbles.
4. Cut 6 slices of French bread diagonally and toast, or pan-fry in a little butter and olive oil. Drain on absorbent paper and place mushrooms on the bread to serve.
