Beef Stir-Fry with Snap Peas

In a medium saucepan with a lid, bring 2 cups salted water to a boil. Add rice; return to a boil. Stir once, and reduce to a simmer. Cover, and cook until rice is tender, 15 to 20 minutes. Remove from heat; let stand, covered, 5 minutes, then fluff with a fork. Ten minutes before rice is done, place steak in a medium bowl. Sprinkle with cornstarch, and season with salt and pepper; toss to coat. In a large skillet, heat oil over medium-high. Cook half the steak until browned on one side, 1 to 2 minutes (steak will cook further in step 3); transfer to a plate. Repeat with remaining beef. Add snap peas, white part of scallions, ginger, red-pepper flakes, and 3/4 cup water to skillet; season with salt and pepper. Cook until snap peas turn bright green, 1 to 2 minutes. Return steak to skillet until cooked through, 1 to 2 minutes. Remove from heat, and mix in green part of scallions and lime juice. Serve with rice.
