Boil the water for the pasta adding 1 tsp oil to keep it from boiling over when you are cooking the pasta. Cook the pasta until slightly less done than you would like it. Thaw spinach in microwave if it is still frozen.
Meanwhile, add 2 tsp oil to a large nonstick skillet or any large pan you have available over medium-high heat. Add ground turkey, bacon, onion, garlic, seasoning salt, worcestershire sauce, and italian seasoning and cook turkey, breaking it up as you go along until it is thoroughly cooked.
Add mushrooms and cook until tender.
Add tomatoes and bring mixture to a boil. Meanwhile, ring spinach out to get all of the moisture you can out of it. Chop finely.
Drain pasta and add to mixture along with spinach. Continue to simmer until pasta and spinach are tender.
Sprinkle cheese over top and serve (with additional cheese if desired).
