Green Cabbage and Apple Sauté

In a large bowl, toss the cabbage with the wine, lemon juice and sugar. Let marinate for 1 hour, tossing often.
In a large deep skillet, heat the olive oil. Add the onion and cook over moderate heat until golden, about 8 minutes. Add the cabbage and its marinade and cook over moderately high heat, tossing, until wilted, about 5 minutes. Cover and cook over moderately low heat, stirring occasionally, until almost tender, about 20 minutes. Add the apples and toss well. Cover and cook, stirring occasionally, until the apples are just tender, about 10 minutes. Season with salt and pepper and serve.

Make Ahead The cabbage and apples can be refrigerated overnight.
