Baked Pastry with Caramelized Onions and Blue Cheese

This is such an easy appetizer and very popular , even amongst the people who apparently hate blue cheese.
I love to use Roquefort, but a milder choice could be Gorgonzola or just a simple, cheaper, Danish blue cheese will do.
Prepare this ahead and bake it while you pour your guests a glass of beautiful red wine.
Easy, cozy and always a big success !

Ingredients:
1 Sheet of puff Pastry.
5 Red onions, peeled and chopped.
2 tablespoons of Balsamic vinegar.
1 teaspoon fine brown sugar.
1 tablespoon butter.
2 tablespoons olive oil.
160 gr. Blue cheese (any kind you like)



Heat the olive oil, together with the butter in a large sauce pan .
Stir in the chopped onions and let them simmer on a low heat, for about 15 minutes, until they are soft and have a golden color.
Add the balsamic vinegar and the brown sugar, stir and cook for another 15 minutes.
Preheat the oven to 200 degrees Celsius .
Meanwhile lay the pastry on a baking sheet , sprinkle the blues cheese all over and finish with your caramelized onions.
Bake for 15 to 20 minutes, use a pizza cutter and cut into squares.
Serve warm with your wine and a green salad .
