Slicing tomato Is Also known as beefsteak tomatoes, this group of tomatoes produces medium to large fruits that are often sliced for topping burgers and sandwiches and is one of the top 10 must-grow plants. Often red but also available in yellow and green varieties, slicers tend to be disease-resistant and easy to grow. Some of the most popular slicers include 'Better Boy' and 'Celebrity'. Several heirloom tomatoes are also excellent slicers. 'Brandywine' is a pink-skin heirloom with soft flesh and full flavor. Lycopene, a flavonoid antioxidant, is a unique phytochemical compound found in the tomatoes. Red variety fruits tend to possess more of this antioxidant. Together with carotenoids, lycopene may help protect cells and other structures in the human body from harmful oxygen-free radicals.
