2 potatoes, peeled and cubed (slightly larger than zucchini cubes)
2 zucchini, cubed
Ground black pepper
1 teaspoon dry Italian seasoning (or a combination of oregano and thyme)
Chopped parsley, for garnish (optional)
Heat a 12-inch straight-sided skillet. Add oil, onion, and butter. Add potatoes and cook 10 minutes, stirring occasionally. Add zucchini, salt, pepper, and Italian seasoning and saute 8 to 10 minutes more, until zucchini are just tender. To serve, garnish with parsley.
