Preheat oven to 350 degrees Fahrenheit.

Heat oil in a sauté pan over medium heat. Add onion and garlic and sauté until onion is beginning to soften, about five minutes. Add zucchini, and red and yellow peppers. Cook until vegetables are soft, about 15 minutes. Remove from heat. Add potato starch, egg, salt and pepper.

Lay each cutlet on a flat surface and place one heaping tablespoon of the vegetable mixture in the center. Roll up the cutlet as tightly as possible and place in a baking pan with the seam side down.

Prepare the sauce. Heat oil in a small saucepan. Add shallots and sauté for three to four minutes. Add mushrooms and cook until softened, about 8 to 10 minutes. Add red wine. Lower heat and cook for at least 10 to 15 minutes, reducing the wine to almost half.

Add chicken soup, potato starch, garlic, salt, and pepper. Let simmer an additional five minutes. It will thicken just a bit.

Pour sauce over cutlets. Bake for 35 to 40 minutes. Serve hot.
