Cozy Italian comfort meets macro-friendly fuel. Tender 90/10 ground-beef meatballs simmered in tomato sauce and tomato paste with white onion, garlic, and parsley, tossed with rigatoni so the ridges catch every bit of sauce. A touch of heavy cream, unsalted butter, and skim-milk cheese adds a rich, velvety finish without going overboard. Satisfying carbs, a strong hit of protein, and classic red-sauce flavors make this meal prep an easy weeknight win.
