Peppery Chicken, Celery, and Potato Stew

Made this up yesterday from what I had available - so good! Fry onion (1 large), celery (6 stalks), chicken (300g), bell peppers (3), and potatoes (750g) until browned. Add white wine (250ml), cream (250ml), and milk (250ml) until covered. Season with chervil (or parsley), garlic salt, and black pepper. Chilli flakes to taste. Dash of Worcestershire sauce. Simmer until reduced to creamy sauce. Serve with salad, and enjoy! :-)
