Prepare the Spiced Lamb:

1. Heat the olive oil in a large skillet over medium-high heat.

2. Add the diced onion to the skillet. Cook it until softened and translucent, about 5 minutes.

3. Add minced garlic to the pan and cook for another minute, allowing it to release its fragrance.

4. Add the ground lamb to the skillet, breaking it up with a spoon. Continue cooking for about 6-8 minutes, until the lamb is browned and cooked through.

5. Season with the spices: Add cumin, coriander, paprika, cinnamon, allspice, and cayenne pepper (if using). Stir everything together and cook for another minute, allowing the spices to bloom and release their full aroma.

6. Stir in the tomato paste and cook for an additional 2 minutes. The tomato paste adds depth and richness to the lamb mixture.

7. Season with salt and pepper to taste.

8. Add the pine nuts (if using) and cook for another 2 minutes, giving the mixture a nutty texture.

9. Remove from heat and stir in freshly chopped parsley for a burst of freshness.

Prepare the Hummus:

1. In a separate bowl, mix the prepared hummus with tahini, lemon juice, and olive oil. Stir until smooth and creamy.

2. Taste and adjust seasoning: You can add a pinch of salt or extra lemon juice to adjust the flavor to your liking.

Assemble the Bowls:

1. Spread the hummus generously in the bottom of each serving bowl.

2. Top with the spiced lamb: Place the cooked lamb mixture in the center of the hummus.

3. Arrange fresh vegetables (cucumber, tomatoes, red onion) around the lamb to add freshness and crunch.

4. Garnish with fresh herbs: Sprinkle fresh mint leaves and parsley over the dish for a refreshing pop of color and flavor.

5. Drizzle with olive oil for a finishing touch, adding richness to the dish.

6. Serve with lemon wedges and warm pita or flatbreads on the side.
