Ingredients:
2 teaspoons olive oil
2 teaspoons butter
2 large yellow onions, peeled and thinly sliced
1 teaspoon salt
1 teaspoon sugar
1 large flatbread
Olive oil for brushing
Kosher salt
4 ounces goat cheese, crumbled
Fresh basil, sliced into ribbons

Instructions:
1. Melt the butter and olive oil in a large saute pan over medium-low heat. Add onions and stir to coat. Cook for 20 minutes, stirring occasionally. Sprinkle the sugar over the onions and continue to cook for another 30 minutes to 1 hour, stirring occasionally. You’re looking for a deep, rich brown color. They may start to stick to the pan a little. It’s OK if they form a bit of a crust, but don’t let them burn. Set aside to cool when done.
2. Preheat oven to 425 degrees.
3. Place flatbread on baking sheet. Brush flatbread with olive oil and sprinkle with salt. Top flatbread with caramelized onions and crumbled goat cheese. Bake for 6-10 minutes, depending on the thickness of your bread. (The cheese should start to melt and the edges of the bread should start to brown.)
4. Remove from oven and sprinkle with basil. Cut into pieces and serve.
