Place olive oil, onion and red pepper in a large saute pan over medium-high heat. Saute until the vegetables begin to sweat (cook without turning brown). Add the ground turkey and garlic; stir to combine until the turkey is cooked through (10 minutes). Add sauce and bring to boil. Reduce heat and simmer for 10 minutes. Remove from heat.
In a frying pan with a touch of olive oil cook the spinach until wilted. Chop and add to the following cheese mixture.

Spread half the cheese mixture over the turkey mixture. Repeat layers ending with the remaining turkey mixture.
