1. Preheat the oven to 180°C (350°F).
2. Pour a few drops of oil into a skillet over medium heat, add the sausage rounds and fry, stirring regularly, until cooked but not too crispy. Set aside.
3. Heat the butter in the same skillet and caramelize the onion strips over medium heat for 20 minutes or until golden brown. Remove from heat and set aside.
4. Place the pizza shell on a large, lightly oiled baking sheet. Brush on a thin coating of olive oil.
5. Place the crème fraîche in a small bowl, add garlic purée, season and mix well.
6. Spread the seasoned cream over the pizza shell. Top with the caramelized onion and sausage and sprinkle with cheese and parsley.
7. Bake in oven for 20 minutes. Serve immediately!

NOTE

If using yellow onions, you can add 5 mL (1 tsp.) of sugar to the skillet to help them caramelize.
