6 tablespoons olive oil, divided
2 medium Golden Delicious apples, peeled, cored, cut into 1/2-inch cubes
1 cup pine nuts
3 shallots, finely chopped
1 cup raisins (optional)
3 (9-ounce) packages fresh spinach
Heat 1 tablespoon olive oil in each of 2 heavy large pots over high heat. Divide apples between pots and sauté until golden brown around edges, about 3 minutes. Divide pine nuts between pots; sauté until pine nuts are lightly toasted, about 3 minutes. Add 2 tablespoons olive oil to each pot. Divide shallots and raisins between pots; stir to combine. Divide spinach between pots; cover and cook just until wilted, stirring occasionally, about 2 minutes. Season with salt and pepper; transfer to bowl and serve.
