Orange Beef Stir-Fry

Directions

1. Cook rice according to package instructions; set aside. Meanwhile, in a small bowl or liquid-measuring cup, combine orange juice, vinegar, soy sauce, and sugar; set aside. In a medium bowl, toss beef with cornstarch; season with salt and pepper. Set aside.
2. In a large skillet, combine broccoli with 1 cup water; season with salt and pepper. Bring to a boil over medium-high; cook, partially covered, until broccoli is bright green and crisp-tender, 4 to 6 minutes. Transfer to a plate. Discard any water in skillet; wipe with paper towel.
