Tomatoes
Is it a fruit or a vegetable? Answer: fruit! This sweet and confusing treat is just as good raw as it is cooked. To find the most delicious and nutritious tomatoes, look for ones that are deep and even in color, as well as firm and heavy for their size. To keep them fresh longer, store them in the butter compartment. And to get them to ripen up quickly, place tomatoes in a brown paper bag. Tomatoes contain lycopene, vitamin C, beta-carotene, potassium, fiber and B6—all of which protect against heart disease and promote optimal health and fitness.
