Step 1: In a small bowl, combine lukewarm water, sugar, and yeast. Let it sit for 5-10 minutes until frothy.
Step 2: In a large mixing bowl, combine the flour and salt. Create a well in the center and pour in the yeast mixture. Knead for about 10 minutes by hand or 5 minutes in a stand mixer until the dough is smooth and elastic.
Step 3: Place the dough in a lightly oiled bowl, cover with a damp cloth, and let it rise in a warm place for about 1 hour or until doubled in size.
Step 4: While the dough rises, prepare the topping. In a food processor or by hand, finely mince the onion, garlic, red pepper, and tomatoes. Drain any excess liquid.
Step 5: Mix the minced vegetables with the meat, parsley, tomato paste, pepper paste, and spices (paprika, cumin, red pepper flakes, salt, and pepper) until well combined.
Step 6: Preheat your oven to 475°F (245°C). If using a pizza stone, place it in the oven to heat up.
Step 7: Punch down the risen dough and divide it into 8 equal pieces. Roll each piece into a ball.
Step 8: On a floured surface, roll out each ball into a very thin circle or oval, about 10-12 inches in diameter.
Step 9: Spread a thin, even layer of the meat mixture over the dough, pressing it down slightly with your fingers so it sticks.
Step 10: Carefully transfer the flatbread to the preheated stone or baking sheet. Bake for 5-8 minutes until the edges are golden brown and crispy and the meat is cooked through.
Step 11: Remove from the oven and immediately cover with a clean kitchen towel to keep them soft enough to roll. Serve hot with lemon, onion, and parsley.
