Double the potato mixture, and use half to accompany the Basic Grilled Flank Steak. Refrigerate leftovers to use in this salad. If you prefer less of a bite, reduce the amount of red and black pepper by half.
Combine potatoes, 1 tablespoon oil, and 1/4 teaspoon salt on a baking sheet coated with cooking spray; toss well to coat. Bake at 450° for 30 minutes or until tender. Place potatoes in a large bowl. Add Basic Grilled Flank Steak and green onions; toss to combine.
Combine remaining 1 tablespoon oil, remaining 1/4 teaspoon salt, juice, and peppers, stirring with a whisk. Drizzle over potato mixture; toss gently to coat. Cover and chill.
