Preheat oven to 400°F (200°C).

Pour Caesar dressing into a baking dish large enough to fit the chicken in one layer.

Place the chicken in dressing and flip to coat.

Bake for 20-25 minutes until chicken is cooked through.

Remove the dish from the oven, set broiler to high, sprinkle the chicken with parmesan cheese, and broil until cheese is melted and golden, about 1-2 minutes. Serve.

Heat the oil in the pan over medium heat.

Add the garlic and sauté for a minute or two until fragrant.

Over high heat, add the spinach, salt, and pepper and stir rapidly until spinach has wilted.

Serve.
