Heat a pot of water for pasta, season with salt and cook pasta to al dente.
Preheat oven to 450 degrees F or broiler.
While pasta water comes to a boil, heat 2 tablespoons oil in a high sided skillet over medium-high to high heat. When the oil smokes, add the pancetta, sirloin and bay leaf and caramelize the meat, 5 to 6 minutes, season with salt, pepper and allspice. Add grated vegetables and garlic, rosemary. Cook 7 to 8 minutes, stir in stock. Add tomatoes and break up with a spoon. Drain pasta and add to sauce then stir in ricotta. Top pasta with a layer of mozzarella and place in oven. Cook 5 minutes to melt and bubble mozzarella.
Dress the escarole and onions with the lemon juice and 3 to 4 tablespoons oil, season the salad with salt and pepper.
