Bring a skillet sprayed with nonstick spray to medium-high heat on the stove. Add mushroom slices & cook them until softened, about 6 minutes, flipping the slices about halfway through cooking. Remove them from heat & set aside to cool.
Season chicken cutlets with salt, black pepper & garlic powder. Lay the cutlets flat, side by side. Spread a cheese wedge over each cutlet & evenly top them with basil. Place the mushroom slices horizontally over the basil.
One at a time, tightly roll the chicken cutlets up from the bottom & around the filling; secure with toothpicks. Place the chicken rolls in a baking pan sprayed with nonstick spray, seam sides down.
Cover the pan with foil & bake in the oven for 20 minutes.
Carefully remove the foil & return the pan to the oven, uncovered, to bake until the chicken is cooked through, about 15 minutes.
Meanwhile, to make the sauce, combine tomato bisque, sour cream & Italian seasoning in a microwave-safe bowl. Mix well.
Once the chicken is fully cooked, cover the sauce & microwave for 1 minute & then stir well. Remove toothpicks from the chicken rolls, plate them & evenly cover with the sauce.
Garnish with additional basil leaves.
