In a small bowl mix the smoked paprika, coriander, mustard powder, oregano, salt, and pepper.
Pat the chicken breasts dry. Sprinkle both sides with the spices. Pat the spice down to ensure their adherence to the chicken.
Drizzle the olive oil into a non-stick skillet over HIGH heat. Sear the chicken for a minute or two. Lower the heat to MEDIUM. Let the chicken cook for 7 minutes on one side.
Use tongs to turn the chicken breasts over and sprinkle in the crushed garlic. Cook for 5 minutes.
Near the end of cooking, add the knob of butter. Spoon the melted butter over the chicken to coat it.
