In a Dutch oven on
medium-high heat, heat the olive oil. Toss in the onions, cooking for three
minutes. Combine the ground turkey with the onions, then season with salt,
pepper, and Italian seasoning.
For 4-5 minutes, cook the
turkey until it is well done, breaking the meat into bite-sized pieces with a
spatula.
Combine the water, marinara
sauce, and pasta in the pan. For 11-12 minutes, simmer until the pasta cooks
through.
Bring the broiler up to
temperature.
Spread the cheese across the
top of the pasta, then set the dish under the broiler. Cook the pasta for 2-3
minutes or until the cheese melts. Serve with a garnishing of chopped parsley.
