1 1/2pounds green cabbage, cored and thickly sliced (about 12 cups)
Salt
3/4cup finely grated Pecorino Romano or Parmesan, or a mixture (about 1 1/2 ounces)
1/4cup chopped fresh parsley, optional
Instructions
In a large Dutch oven over medium heat, toast the pepper, stirring constantly, until fragrant, about 1 minute. Add the oil and butter and heat them, swirling to melt the butter and combine it with the oil. Add the cabbage and 1 teaspoon salt and cook, tossing and stirring, until the cabbage just begins to wilt, about 5 minutes. Adjust the heat to medium-low, cover the pot, and continue to cook, tossing and stirring occasionally, until the cabbage is very tender, about 20 minutes longer.
Add most of the cheese and parsley, if using, and toss and stir to distribute. Taste and adjust the seasoning with additional salt and pepper, if necessary. Scrape the mixture into a (warmed) serving bowl, sprinkle with the remaining cheese and parsley, and serve immediately.
