Apple Blue Cheese Flatbread with Caramelized Onions

In a small skillet, add the onion, olive oil, salt, and crushed red pepper. Turn the heat to low, and let the onions very slowly cook for 30–45 minutes, stirring every few minutes, until the onions are very dark brown and soft but not burned at the edges.

Preheat oven to 450ºF. Build the flatbreads by layering each with apple butter, onions, walnuts, apple slices, sharp cheddar, and blue cheese crumbles. Place on a baking sheet, and bake for 10–15 minutes until the cheese is bubbly.

Let cool for 5 minutes on the baking sheet, then cut into wedges. Top with the watercress, and serve!
