This is why my entire backyard has turned into a kitchen garden with chickens, to grow for flavor.  Try Granny Cantrell German Red, Carbon, Paul Robeson or Aunt Ruby's German Green for slicers. I like Green Doctors for a cherry, though Igleheart is good and outproduces everything I've grown.  There are also fun things people don't even know exist like a green pepper tomato that was bred to have a seed cavity like a pepper (the two plants are related) for stuffing. And Reisentomate, the "travel tomato" grows in these little lumpy sections so you can remove them one piece at a time for snacking.
