Preheat oven to 350°. Combine green onions, goat cheese, and bacon. Cut a 1-inch-wide slit into the thick end of chicken breast halves, and carefully cut down to center of chicken to form a pocket. Divide cheese mixture evenly among pockets. Secure with wooden picks. Sprinkle chicken with salt and pepper. Heat a large ovenproof skillet over medium-high heat. Add canola oil. Add chicken to pan; sauté 4 minutes. Turn chicken over. Bake at 350° for 12 minutes; let stand 5 minutes.
