Summer salad

Salad
I am a huge fan of vinegars.  Vinegar changes the entire structure of a dressing.  Cider vinegar is the key to a good gazpacho and this particular salad.  Simple easy salads are a standard in our house during the warm months.  This particular salad I read about on Food and Wine.  Quite good.

One Granny Apple, peeled, cored and sliced into matchstick pieces
1 box of grape tomatoes cut in half
1 lb. of green beans, blanched in hot water
1/2 small red onion sliced ( this part I omitted because raw onions upset Jessica's stomach)

Dressing:

1/2 tsp. Dijon mustard
2 T. cider vinegar
1/4 cup olive oil
1 T. boiling water ( sounds strange but it works)

Mix together the mustard, vinegar and water first and then slowly pour the olive oil in while whisking.

That's it.  Easy.  Simple and refreshing.
