Season chicken with salt, pepper, and garlic powder.
Add chicken breasts to the skillet and brown on both sides for 3 - 4 minutes. Cover and reduce heat. Continue to cook on low heat. Chicken is ready when it is temped at 165 F. or juices run clear. Drain juice and set chicken aside on a cutting board. Turn off the heat to the skillet.
Meanwhile, cook fettuccine as directed on the box and drain.
Slice chicken into bite-size pieces.
Place chicken back into the skillet and add Alfredo sauce, fettuccine, broccoli, and bacon. Toss together until everything is coated in sauce. Return heat to low and cover for 5 minutes to heat through.
