Heat oil in a large pan over medium-high heat and add the minced meat and chopped onions. Cook for 5-7 minutes until the meat is cooked through. Season with salt, pepper, paprika powder, curry powder, and garlic. Add the canned pizza tomatoes and chili sauce, then simmer for 5 minutes.
While the sauce simmers, cook the pasta in a large pot of boiling salted water according to package instructions. Add the finely chopped leeks to the pasta water during the last 2 minutes of cooking.
Drain the pasta and leeks, then fold them into the meat sauce. Season to taste with additional salt, pepper, or spices.
