Italian-style gyros with yogurt and tomatoes

Ingredients:

• 350 g raw sweet Italian sausages (about 4 pcs.)
• 2 tsp ground cumin
• 1 teaspoon dried oregano
• 1 tbsp extra-virgin olive oil
• 2 tomatoes, cut into pieces
• 4 medium romaine lettuce leaves, chopped (about 2 cups)
• 0.5 cup Greek yogurt
• 1 teaspoon lemon juice
• 0.5 tsp harissa
• 4 round flatbreads, 15 cm in diameter, such as pitas without pockets

Preparation:

1. Heat a cast iron grill pan or grill surface over medium-high heat.
2. Slice the sausages lengthwise and open them like a book. Remove the rind and press the sausages flat, about 0.5 cm thick. Combine the cumin and oregano in a small bowl. Rub the cut sides of the sausages with the spice mixture. Brush a hot skillet with oil and add the sausages, seasoned side down. Cook on each side until browned and cooked through, 3-4 minutes per side.
3. In a medium bowl, combine the tomatoes and their juices with the lettuce leaves. In another bowl, combine the yogurt, lemon juice, harissa, and 1/4 teaspoon of salt until smooth.
4. Fry each flatbread in a dry frying pan for about 30 seconds on each side. Spread a little yogurt sauce on the flatbreads and top with the tomato-lettuce salad and sausage. Serve with the remaining sauce.
