Heat water for pasta to boil. Salt and cook pasta 7 to 8 minutes, to al dente.
Preheat oven to 425 degrees F.
Heat a deep skillet or medium heavy bottomed sauce pot over medium high heat. Season pork chops with salt and pepper. Halve sausages. Add 1 tablespoon, 1 turn of the pan, extra-virgin olive oil to pan or pot. Place chops in pan or pot and brown 2 minutes on each side, remove. Add another tablespoon oil, 1 turn of the pan, and sausages. Brown sausages 2 minutes on each side and transfer to plate with pork. Add pepper flakes, 3 cloves chopped garlic and onion to the pot and saute 1 minute. Add broth to the pan and scrape up drippings. Add tomatoes and herbs and bring sauce to a bubble. Add meats back to the pot and reduce heat to simmer. Simmer sauce until ready to serve, 12 to 15 minutes.
Combine ground meat, egg, remaining 2 cloves chopped garlic, 1/3 cup cheese, and bread crumbs. Season with salt and pepper and roll into balls, 1 1/2 to 2 inches in diameter. Place balls on nonstick cookie sheet. Roast meatballs 10 minutes, then slide into Sunday sauce and turn off oven. Add bread to oven to crisp crust.
To serve, place pork, sausages and meatballs on serving dish. Pour 1/2 of the sauce into a serving dish to ladle over pasta and meats at the table. Toss cooked spaghetti with remaining sauce in sauce pot, adding a few handfuls of grated cheese to the pot as you toss it. Transfer pasta to a serving dish.
