My two sons and I love these. If they had their way I would have to make 'em in a washtub! I experimented, once and added bell pepper squares. Now, they want carrot slices, tomatoes. You can use virtually any veggie. If cucumbers give you indigestion, try scoring them lengthwise with the tines of a fork. Just deep enough to see the marks. Just below the skin, in the meat, lies a layer of "heartburn". An elderly British friend of my Dad taught me this recipe and that tip. That man could COOK.
