Paper towel dry the chicken and season with salt, pepper and garlic powder. Then set aside.
Heat olive oil in a large deep skillet. Add chicken breasts and cook on each side on medium high heat for about 4 minutes per side (for a total of 8 minutes) until nicely browned. If chicken is still pink in the center, reduce heat to medium and cook covered for several minutes until no longer pink in the center. Remove chicken from pan and slice it.
