I haven’t yet tried this recipe, but have been wanting to use wheat berries and can’t wait to try it.  It got great reviews on epicurious.

 1 cup wheat berries (available at natural food stores/co-ops)
6 tablespoons olive oil
1 cup finely chopped red onion
2 tablespoons balsamic vinegar
3 green onions (scallions), minced
1 carrot, peeled, chopped
1/2 red bell pepper, chopped

 Bring large pot of salted water to boil. Add wheat berries, reduce heat to medium-low and simmer until tender, stirring occasionally, about 1 hour. Drain.

Heat 2 tablespoons oil in heavy medium skillet over medium heat. Add red onion; sauté until tender, about 6 minutes. Remove from heat. Add 4 tablespoons oil, then vinegar; whisk to blend.

Toss wheat berries, green onions, carrot and bell pepper in large bowl. Pour dressing over; toss to blend. Season to taste with salt and pepper. Cool completely. (Can be made 1 day ahead. Cover; chill.)
