Flatbread Pizzas with Ground Meat (Lahmajoun)

Preparation

1. With the rack in the middle position, preheat the oven to 425°F (220°C). Line a baking sheet with a silicone mat or parchment paper.
2. In a skillet over medium-high heat, lightly brown the meat in the oil, breaking it up with a wooden spoon as it cooks. Add the onion, garlic and spices. Continue cooking for 3 minutes. Season with salt and pepper. Remove from the heat.
3. Transfer the mixture to a food processor. Add the tomato, yogurt and herbs. Pulse the mixture a few times until creamy (see note). Adjust the seasoning. 
4. Place the pitas on the prepared baking sheet and spread each one with one-quarter of the meat mixture. Bake for 12 minutes or until the flatbreads are lightly golden. Let cool, then garnish with more parsley and mint.
