Meanwhile, in a pot saute the remaining oil with the onions and garlic. Brown the ground turkey, draining as needed. When meat is fully cooked, add the tomato products, mushrooms, and Italian spice blend. Bring to a boil, then allow to simmer for 30-45 minutes. You want the sauce to be pretty thick and chunky (not very runny). Continue simmering the sauce until it reaches this consistency.
