Start with one firm, large cucumber cleaned well--leave the skin intact for more fiber and nutritional benefits--chopped in bite sized pieces. Add some chopped cherry or grape tomatoes (1/2 cup), try some of the new sunburst grape tomatoes for an added bright taste to your salad. Then add some chopped onion and red or green bell pepper (about 1/4 cup each). Put in a teaspoon or two of chopped dill (fresh or dry) to your taste. Pour 1/8 cup light olive oil or canola oil and 1/4 to 1/3 cup of white vinegar over all those wonderful veggies and mix together well. The easiest way to mix is to put all the ingredients in a plastic container with a tight fitting lid, secure the lid and shake. After mixing, place the salad in the fridge to meld for a few hours before you enjoy a 1/2 cup serving of it.
