Ingredients

1/2 cup red quinoa

1/2 cup white quinoa

1/2 cup semi-pearl farro

1/2 cup pearl barley

1/2 cup purple (black) barley

10 ounces red pearl onions

2 tablespoons plus 1 teaspoon extra-virgin olive oil

1 1/4 teaspoons coarse salt

1/2 teaspoon freshly ground pepper

1/4 cup apple cider

3 tablespoons balsamic vinegar

1/2 cup feta cheese, crumbled (2 ounces)

1/3 cup fresh flat-leaf parsley, leaves only

1 tablespoon finely grated lemon zest

1 small Fuji apple, cored and thinly sliced

Preparation

Preheat oven to 425 degrees. Cook grains; mix them in a large serving bowl.

Cover onions with hot water, and soak for 2 minutes. Peel and halve onions. Place on a rimmed baking sheet, and toss with 1 teaspoon oil, 1/2 teaspoon salt, and 1/8 teaspoon pepper. Roast until caramelized, about 20 minutes. Pour cider over onions, and roast until liquid reduces by half, about 5 minutes. Let cool slightly.

Gently toss grains with onions, vinegar, feta, parsley, lemon zest, and the remaining oil, salt, and pepper. Stir in apple, and serve immediately.
