Eating right doesn’t just help your physical health—it can improve your mental health as well. This open-face sandwich is a bona fide brain booster adapted from Unforgettable: The Bold Flavors of Paula Wolfert’s Renegade Life by Emily Kaiser Thelin. The book chronicles the life of influential cookbook author Paula Wolfert, credited by many with introducing Mediterranean fare to American cooks. (If there’s a box of couscous in your pantry, thank her.) When Wolfert, 79, was diagnosed with Alzheimer’s disease in 2013, she dove into the latest research so she could be sure to include brain-boosting foods in her diet and eliminate any potential brain busters, such as refined carbohydrates and added sugar.
