Combine the ingredients for the vinaigrette and set aside.

Place wheat berries in a colander, rinse under cold running water and drain well. Transfer them to a saucepan, add water and salt. Bring to a boil, reduce heat to low, cover and simmer for one to one and a half hours, until tender. Drain if necessary. Let the wheat berries cool completely.

Combine wheat berries with the remaining salad ingredients in a large bowl and toss.

Add the vinaigrette and mix to combine.
