This recipe calls for you to grill twice as much meat as you will need, so save half for Orange Beef Pasta to serve later in the week.
2 pounds (1-inch-thick) boneless top sirloin steak
3 tablespoons olive oil, divided
2 teaspoons kosher salt, divided
1 teaspoon freshly ground pepper, divided
6 medium-size yellow squash, cut in half
1 red onion, cut into 1/2-inch-thick slices
1 lemon, cut in half
1 (10-oz.) box plain couscous
1/2 (4-oz.) package crumbled feta cheese
Chunky Cucumber-Mint Sauce
How to Make It
Preheat grill to 350° to 400° (medium-high). Rub steak with 1 Tbsp. oil, 1 1/2 tsp. kosher salt, and 3/4 tsp. pepper.
Brush squash and onion with remaining 2 Tbsp. oil; sprinkle with remaining 1/2 tsp. kosher salt and 1/4 tsp. pepper.
Grill steak and vegetables, covered with grill lid, over 350° to 400° (medium-high) heat 5 to 7 minutes on each side or until steak reaches desired degree of doneness and vegetables are tender. Remove steak and vegetables from grill; squeeze juice from lemon over steak and vegetables. Cover steak and vegetables with aluminum foil, and let stand 10 minutes.
Meanwhile, prepare couscous according to package directions.
Cut steak across the grain into thin slices. Cover and chill half of sliced steak (about 1 lb.) up to 2 days. Top couscous with vegetables; sprinkle with feta cheese. Serve with remaining half of steak and Chunky Cucumber-Mint Sauce.
