Caramelizing onions takes some time, so start by bringing a pan to medium-high heat with Olive Oil (2 tablespoon). Add the Yellow Onion (1) and salt, but turn the heat to low. Stir regularly over low heat until caramelized, which can take up to 40 minutes. Feel free to speed up this process by cooking the onions over slightly higher heat, but expect a less caramelized effect (it will still taste great).
While the onions caramelize, make the dough by mixing the All-Purpose Flour (1 cup), Vegetable Oil (1 1/2 tablespoon), Water (1/2 cup), and Salt (1 pinch) by hand. Knead well, adding additional flour until the dough is not at all sticky. Allow it to just sit there and rest while you pull the other ingredients together.
Preheat the oven to 500 degrees F (260 degrees C).
In a small bowl make the sauce by mixing the Fat-Free Greek Yogurt (1/4 cup), Balsamic Vinegar (2 tablespoon), and Horseradish (1 tablespoon).
Slice the Fig (5). Place your baking sheet in the oven to heat up.
When the onions are ready, remove from the pan and set aside. Now roll out your dough on a large piece of floured parchment paper, getting it as thin as possible without breaking.
Sprinkle the baking sheet with Breadcrumbs (as needed) and transfer the dough to the sheet as quickly as possible.
Working at lightning speed (or close to it), layer the sauce, onions, figs, and Goat Cheese (2 ounce) on the dough.
Bake for 15 minutes, or until browned to your liking.
Garnish with Fresh Parsley (to taste). Enjoy your perfectly baked crispy flammekueche!
