Wheat Berry Salad with Caramelized Onions and Grapes

Cook wheat berries in boiling, salted water, until they are cooked but still quite crunchy, about 55 to 60 minutes. Drain and transfer to large bowl. 

Meanwhile, heat 5 tablespoons of oil in large, heavy skillet over medium heat. Add onions and cook, stirring frequently, until dark brown, about 25 to 30 minutes. 

Stir onions into drained wheat berries and cool slightly. 

Stir in thyme, grapes and arugula.

Using chef’s knife, mash and chop garlic on cutting board with salt until it becomes paste. 

Transfer paste to bowl and add vinegar, pepper and remaining oil. Blend well; pour over salad. 

Mix salad well, sprinkle with feta and serve.
