Heat a Dutch oven over medium high. Once hot, add olive oil and saute your carrots, celery and onion about 4 minutes or until softened. Then add your beef and pork. Cook breaking it up until fully brown. Then add your garlic and tomato paste. Cook for 1 minute, then add your canned tomatoes, basil, salt, pepper and milk. Bring to a simmer and cook covered for 2- 2 1/2 hours.
Boil your fettuccini to packaged directions in salted water. Drain and save some pasta water.
In a pan over medium low heat, add a large spoonful of your sauce and some cooked fettuccine. Then add a splash of pasta water and toss until the pasta is coated with the sauce. Add to a bowl and top with more sauce, parmesan cheese and basil. Enjoy!
