Pulse the onion, celery, carrot, garlic and rosemary in a food processor until finely chopped.
Heat the olive oil in a large saucepan over medium-high heat. Add the chopped vegetables and cook, stirring, until softened and golden, 3 to 5 minutes. Add the veal, 1 teaspoon salt and 1/2 teaspoon pepper and cook, breaking up the meat with a wooden spoon, until no longer pink, about 3 minutes. Add the tomatoes, milk, 1 cup water and 1/2 teaspoon salt. Bring to a boil, then reduce the heat and simmer until slightly thickened, about 20 minutes.
Meanwhile, bring a large pot of salted water to a boil and cook the fettuccine as the label directs. Drain the pasta, then toss with half of the ragu (about 3 cups). Top with parmesan. Reserve the remaining ragu to make stuffed peppers.
