Pierce potatoes with fork several times; place on microwave-safe plate. Microwave on High for 6 to 8 minutes or until fork-tender, turning once.
Meanwhile, in 12-inch nonstick skillet, break up ground beef; sprinkle with seasoned salt and pepper. Cook over medium-high heat until beef is thoroughly cooked, stirring frequently. Drain.
Stir in broccoli, bell pepper and Alfredo sauce. Reduce heat to low; cook about 6 minutes or until broccoli is crisp-tender, stirring occasionally.
Place potatoes on individual serving plates. Cut potatoes in half lengthwise; mash slightly in skin. Top each potato half with beef mixture; sprinkle with basil.
