In a pan, heat oil to medium-high. Add the vegetables and brown them for 5 minutes. Add the ground lamb, salt and pepper, then cook until the meat starts to brown with caramelized spots. Deglaze with the white wine. Blend in the tomato paste and diced tomatoes, and bring to a boil. Add spices and chopped garlic, then simmer for 30 minutes while stirring regularly. Meanwhile, cook the pasta in a large quantity of lightly-salted water. Drain and serve with the bolognese sauce over top.
