Preheat the oven to 425°F (220°C). Grease a baking sheet with nonstick spray.
2. Step
Roll out the pizza dough and cut in half lengthwise (save the other half for another use). Place the dough on the prepared baking sheet and use your fingers to stretch and shape it into an oval.
3. Step
Melt the butter in a small saucepan over medium-low heat. Add the garlic and cook for 2–3 minutes, or until just starting to brown. Remove the pot from the heat and whisk in the Frank's RedHot®.
4. Step
Spread half of the Frank’s RedHot® butter over the dough, then top with the feta, mozzarella, and Parmesan cheeses.
5. Step
Bake the flatbread for 10–15 minutes, or until the crust is golden brown and the cheese is melted.
6. Step
Top with the rest of the Frank’s RedHot® butter and the parsley. Cut into 8 slices, then serve.
