1 apple, peeled if necessary, cored and coarsely grated;
1⁄2 teaspoon kosher salt, plus more to taste;
1⁄2 teaspoon ground black pepper, plus more to taste;
1⁄2 to 3⁄4 cup chicken or vegetable stock or apple cider, divided.
How to make
Beginner greens
Wash and dry the greens. Discard the large stems and any tough inner ribs. Thinly slice the leaves.
Heat the butter and oil in a large skillet over medium-high heat. When the butter foams, add the onion and a pinch of salt and cook, stirring frequently, until the onion softens and turns golden, about 10 minutes. Stir in the apple and cook, stirring often, until crisp-tender, about 3 minutes.
Add the greens one handful at a time and stir to coat with the butter and oil. Let each addition cook down a little before adding the next. Cook, tossing the greens constantly with tongs, just until they wilt, 1 to 3 minutes, depending on the size and type of the greens.
Add the salt, pepper, and 1⁄2 cup of the stock. Cover the pan and simmer until tender, 1 to 5 minutes. Add a splash of the remaining stock if the greens get dry. Check the seasoning and serve warm.
What else works? You can use a chopped ripe tomato instead of the apple.
