One store bought pizza dough
4 large sweet onions, sliced in rings
2 tbsp. unsalted butter
2 tbsp. extra virgin olive oil
1 tbsp. sugar
3 tbsp. cider vinegar
4-6 oz crumbled feta cheese
1/4 cup pine nuts or chopped walnuts (depending on which you prefer)
salt and freshly ground pepper to taste
Preheat the oven to 450 F. If using a baking stone place in oven to preheat. Shape the dough into one large round. Place on floured peel for easy transfer into the oven. Meanwhile, in a frying pan over low heat melt the butter and oil. Fry the onions stirring regularly to avoid burning, about 20 minutes. They should be very soft, add a little water as needed if they begin to stick. Add the sugar and vinegar and continue to cook until the vinegar evaporates. Add salt and pepper to taste. The onions should have a golden brown hue.
Top the pizza with the onions to cover. Sprinkle with the nuts and then the cheese. Place into the oven and bake for approx. 10 minutes. Reduce the heat to 400 and bake until the crust is golden. Remove from oven and allow to sit for approx. 10 minutes.
