Thyme is rich in zeaxanthin and lutein, both of which can reduce the risk of eye disease like age-related macular degeneration and cataracts. Studies have indicated that these powerful antioxidants aid in improved vision when there’s dim light. Aside from boosting eye health, this recipe contains an excellent source of selenium, B vitamins, and vitamin D from mushrooms—all of which can help with energy production and mood regulation.

1. Preheat the oven to 350°. Heat the butter and olive oil over high heat in a heavy saucepan or skillet large enough to hold the chicken breasts in one layer. When the oil smokes, add the chicken breasts and season them with the salt and pepper. Sauté until golden brown, about 3 minutes on each side. Transfer to an oven-safe dish, and bake until the juices run clear when pierced with a knife, about 25 minutes. Remove to a plate, and keep warm.
2. Add the onion, garlic, and mushrooms to the drippings in the pan, and cook for about 1 minute over high heat. Add the vinegar and thyme, and continue cooking for about 1 minute. Add ½ cup of water, and cook until the liquid is reduced by half. Season to taste. To serve, slice each breast in half crosswise on the diagonal. Coat the chicken with the sauce, and sprinkle with chives.
