Add beef to the vegetables and cook, breaking up with a wooden spoon, until cooked through, 3 to 4 minutes. Increase heat to medium-high, add wine and cook until almost evaporated, 1 to 1 1/2 minutes. Stir in tomatoes, tomato paste and nutmeg; reduce heat to medium-low, cover and simmer, stirring occasionally, for 10 minutes. Remove from the heat and stir in salt and pepper. Serve the pasta with the sauce.
