Begin by generously seasoning both sides of the chicken cutlets with a sprinkle of salt and a dash of pepper. This initial seasoning will create a flavorful base for your Chicken Florentine.

In a pot, heat the oil over medium-high heat until it's nicely warmed. Gently place the seasoned chicken cutlets into the pot, and let them sizzle and sear for approximately 3 minutes on each side.

Next, introduce the spinach leaves to the same pot. Stirring gently, let the spinach mingle with the chicken.

As the spinach wilts, it's time to prepare a smooth sauce. Dilute the cornstarch in the chicken broth, ensuring no lumps remain. Pour this mixture into the pot with the chicken and spinach, and increase the heat to high. Allow the flavors to meld as the sauce thickens for about 5 minutes.

With the sauce at a simmer, introduce the low-fat yogurt and grated parmesan cheese. Stir these ingredients into the pot until they're fully integrated. Cover the pot and let the sauce gently simmer for an additional 2 minutes, allowing the flavors to meld harmoniously. To serve, plate your Chicken Florentine alongside a side of steamed vegetables or your favorite accompaniment.
