Directions

1. Heat broiler, with rack set 4 inches from heat. Line a broiler pan with aluminum foil; set aside.
2. In a large skillet, heat cup oil over medium. Add potatoes and cook, turning frequently with a thin metal spatula, until golden and crisp-tender, 15 to 20 minutes. Add peppers; season with salt and pepper. Continue to cook, tossing occasionally, until vegetables are tender, about 10 minutes more.
3. Meanwhile, rub beef with remaining teaspoon oil; season with paprika, salt, and pepper. Broil, turning once, until medium-rare (an instant-read thermometer inserted in thickest part should register 130 degrees), 10 to 15 minutes. Transfer to a plate, cover loosely with aluminum foil, and set aside to rest, 5 to 10 minutes. Thinly slice beef against the grain, and serve with vegetables.
