Preheat the oven to 350°F.
Coat a small skillet with olive oil spray and heat over medium heat. Add the turkey and garlic. Sauté for 7 minutes, stirring occasionally, breaking the turkey into crumbles.
For the Marinara:
Heat the olive oil in a medium pot. Sauté the onion in the oil until translucent, about 10 minutes. Add the garlic and stir. Add the broth, tomatoes and bay leaf. Simmer, uncovered, over low heat until the sauce thickens, about 1 hour. Remove the bay leaf, stir in the basil, and voila - delicious! Store in an airtight container in the refrigerator.
