Ingredients

1 cup orzo

Coarse salt and freshly ground pepper

6 tablespoons extra-virgin olive oil

Finely grated zest of 1 lemon, plus 2 tablespoons juice

1 shallot, minced (about 2 tablespoons)

2 teaspoons packed finely chopped fresh oregano leaves

2 boneless, skinless chicken-breast halves (about 6 ounces each), butterflied, sliced in half, and pounded 1/4 inch thick

9 ounces thawed frozen artichoke hearts, patted dry

1 to 2 romaine-lettuce hearts, trimmed and leaves separated

Preparation

Cook orzo in a pot of salted boiling water until al dente, about 7 minutes. Meanwhile, whisk together 5 tablespoons oil, lemon zest and juice, shallot, and oregano; season with salt and pepper. Drain orzo, transfer to a bowl, and toss with half of dressing.

Season chicken with salt and pepper. Heat a large skillet over medium-high heat. Swirl in remaining 1 tablespoon oil; add chicken in a single layer. Cook, flipping once, until golden and just cooked through, 1 to 2 minutes a side. Transfer to a plate. Add artichoke hearts to skillet; cook, stirring, until warmed through, about 1 minute. Transfer to bowl with orzo. Shred chicken; add to orzo with remaining dressing. Toss to combine; season with salt and pepper. (Store in refrigerator up to 2 days.) Serve in lettuce cups.
