In a small bowl, mix 1 1/2 tablespoons
Dijon mustard, 1/2 teaspoon salt and 1/4 teaspoon pepper. Heat 2 tablespoons olive oil over medium high heat in a large skillet. Coat chicken with Dijon/salt/pepper mixture and add to sizzling skillet. Sear chicken until golden, approximately 3-5 minutes per side (its okay if some of the Dijon comes off), remove to a plate. (Chicken will finish cooking with rice)
