Sprinkle 1 pound of chicken cutlets with ¼ teaspoon each salt and pepper.
Heat 1 tablespoon oil in a large skillet over medium heat.
Add the chicken and cook, turning once, until browned and cooked through, about 6 minutes. Transfer to a plate.
Add 3 cloves garlic to the pan and cook, stirring, for 30 seconds.
Increase heat to medium-high and add ½ cup wine. Cook until slightly reduced, about 1 minute.
Return heat to medium and stir in 2 cups spinach, ½ cup cream and the remaining ¼ teaspoon each salt and pepper. Simmer for 2 minutes.
Return the chicken to the pan and turn to coat with the sauce.
