Beef and Broccoli Stir Fry

3 tablespoons soy sauce
3 tablespoons apple juice
1 tablespoon cider vinegar
1 tablespoon sugar
3 cloves garlic, minced
Ground pepper
1 1/4 pounds flank steak, cut diagonally across the grain into 1/2-inch-by-3-inch strips
1 tablespoon plus 1 teaspoon canola oil
1 tablespoon cornstarch
1 head broccoli, stems trimmed, peeled, and cut into 1/4-inch rounds, florets separated into bite-size pieces
Coarse salt

In a large, shallow bowl, mix soy sauce, apple juice, vinegar, sugar, garlic, and 1/4 teaspoon pepper. Add meat; toss to coat. Let marinate 15 minutes. Transfer meat to a plate; reserve marinade.

Heat 1 tablespoon oil in a 12-inch nonstick skillet over high heat.  In two batches, cook            meat until lightly browned, turning once, about 2 minutes per batch. Remove meat. Add 1/2 cup water to pan; stir up browned bits with a wooden spoon. Pour into marinade; whisk in cornstarch.

In same skillet, stir fry broccoli in remaining teaspoon oil over high heat until bright green and crisp, tossing often, 2 minutes. Add 3/4 cup water; cook until broccoli is tender, 6 to 8 minutes. Remove from pan

Stir marinade, add to pan, and bring to a boil, stir, until thickened. Return meat and broccoli to the pan; toss to coat.  Season with salt and pepper. Serve immediately over rice.
