Creamy Skillet Potatoes

Combine following ingredients:
4 to 5 medium potatoes, peeled and cubed
1/3 cup Onion, chopped
1 envelope ranch-style dressing mix (1 ounce)
1/3 cup sour cream
2 cups milk
1 teaspoon parsley

Precook potatoes in microwave or boil until slightly tender. Spray a large skillet with non-stick cooking spray. Over medium heat, brown onions and potatoes. Add remaining ingredients and simmer just until sauce thickens.
