Heat large skillet to medium high heat, add olive oil and ground turkey. Saute turkey until no longer pink, be sure to chop the turkey with a spatula to break the turkey into small pieces. About 5-7 minutes.
Next add garlic cloves, dry basil, dry oregano, fennel seeds, and salt. Stir to mix and saute for 1 minute.
Add in the diced tomatoes, stir and cook for an additional 5 minutes to let flavors cook together.
