This easy ragù is made with a secret shortcut ingredient--a jar of marinara sauce! Be sure to use a top-quality sauce (I like Rao's) for the best flavor. My supermarket sells turkey in 1 1/4-pound packages. A 1-pound package will work fine, too. Serve over pasta, rice, couscous, or polenta.
Heat the olive oil in a large pot, Dutch oven, or skillet with high sides. Add onion and saute until translucent, about 5 minutes. Add the garlic and cook until fragrant, about 1 minute.
Add the turkey, and cook, breaking up with a wooden spoon, until no longer pink, about 5 minutes. Stir in the spices and marinara sauce. Bring to a boil, then reduce the heat and simmer until the turkey is cooked through and the sauce has thickened slightly, 15 to 20 minutes.
Stir in the spinach and raisins and cook just until the spinach is wilted, about 2 minutes. Taste, and season with salt and pepper as needed.
