russian cucumber and tomato salad

My daughter took this salad to school today for her class's international feast after having studied Russia.  This salad is wonderful and we actually took some back to school for her teacher who loved it.  Very simple salad and very yummy.

russian cucumber and tomato salad (Natasha's Kitchen)
4-6 medium Roma tomatoes (2 pounds)
4-5 small cucumbers or 1 English cucumber (1 pound)
1 small onion, thinly sliced
2 tablespoons extra virgin olive oil
1 tablespoon distilled white vinegar
3/4 teaspoons table salt
1/4 teaspoon pepper to taste
2 tablespoons green onion, sliced

Slice tomatoes and cucumbers and place them in a large bowl.  Thinly slice onion and add them to the salad bowl.  Add sliced green onion.  In a small bowl, stir together 2 tablespoons oil, 1 tablespoon vinegar, 3/4 teaspoon  salt, 1/4 teaspoon pepper.  Just before serving, drizzle your salad with dressing and add more slat to taste if desired.  Don't add the dressing early or the tomatoes will be too juicy.
