Crispy Cucumbers and Tomatoes in Dill Dressing

This recipe comes from allrecipes.com.  I was looking for a great summer salad, and this is what I found, made, and received rave reviews. I doubled the recipe and used half cider vinegar and half balsamic vinegar.

Ingredients:
1/4 cup cider vinegar
1 tsp white sugar
1/2 tsp salt
1/2 tsp chopped fresh dill weed
1/4 tsp ground black pepper
2 tbsp vegetable oil
2 cucumbers, sliced
1 sliced red onion
2 ripe tomatoes, cut into wedges

Directions:
In a large bowl, mix together vinegar, sugar, salt, dill, pepper and oil.  Add cucumber,
onion, and  tomatoes.  Toss, and let stand for at least 15 minutes before serving.
