How to Make It
Cook bacon in a large skillet over medium until crisp, about 10 minutes, turning halfway through. Remove and crumble bacon, reserving drippings in skillet. Add endive to skillet, and cook, stirring occasionally, until golden brown and tender, about 15 minutes. Stir in spinach, and cook until wilted, about 1 minute. Transfer mixture to a medium bowl; let stand 30 minutes.
Add bacon, sour cream, chives, lemon juice, salt, and pepper to endive mixture; stir to combine. Serve with assorted crudités.
