Bring a large pot of salted water to a boil. Cook pasta for about 8-10 minutes until al dente, then drain and return to pot. Drizzle with olive oil and toss.

Heat olive oil in a large skillet, add chopped onions, and sauté until translucent. Incorporate ground beef, cooking until browned. Stir in spices and tomato sauce.

In a mixing bowl, combine yogurt, tahini, garlic, dried mint, and salt. Mix gently to retain thickness.

Toast pine nuts in a small pan over low heat, stirring frequently until golden brown.

To serve, layer cooked pasta, meat mixture, and yogurt sauce in a serving dish. Garnish with toasted pine nuts and herbs.
