Microwave on high 8 minutes or until tender. Drain. On jelly-roll pan, toss potatoes with 1 teaspoon oil and 1/8 teaspoon each salt and pepper. Broil 6 minutes or until browned. Meanwhile, in nonstick 10-inch skillet, heat 1 tablespoon oil on medium 1 minute. Add green onions and orange pepper; cook 5 minutes or until golden, stirring occasionally.
