Cucumber Salad

I feel like eating cucumber salad today. I bought lots of cucumber yesterday and it's my time to eat them now. Since I was young I love to eat cucumber because we have many in our farm before. Now that I live in the city I always buy in the store it's good for me to lower my bp. Here's the ingredients and procedure:

2 medium cucumbers, thinly sliced
4 green onions, thinly sliced
3 small tomatoes, sliced
2 tablespoons snipped fresh parsley
Dressing:
1/4 cup sour cream
1/4 teaspoon prepared mustard
2 tablespoons minced fresh dill
1 tablespoon vinegar
1 tablespoon milk
1/2 teaspoon salt
1/8 teaspoon pepper

Direction:
In a bowl, combine cucumbers, onions, tomatoes and parsley. Combine dressing ingredients; pour over cucumber mixture and toss gently. cover and chill for at least 1 hour.
