Oven-Baked Spinach Burgers

These spinach- and onion-flecked burgers are filled with brain-boosting vitamin K. For a vegan version, substitute 1 tablespoon ground flaxseed mixed with 3 tablespoons water for the large egg. Fresh kale may be substituted for the spinach; remove all stems, extend sautéing time by 5 minutes, and carefully drain any excess liquid. Serve with horseradish and ketchup.
