Season the chicken well on both sides with garlic powder, paprika, and salt & pepper.
Heat the oil in a skillet or oven safe non-stick pan over medium heat.
Once the pan is hot, add the chicken and cook on both sides for about 4-5 minutes each until they're golden brown.
Place the pan in the oven and cook until the chicken reaches an internal temperature of 160°F using a thermometer.
In a saucepan over low-medium heat, add the cream, mustard, and honey. Season with salt and pepper and bring to a simmer until it reduces and thickens into a creamy sauce (consistency should coat the back of a spoon). Taste and adjust the seasoning with salt or more mustard or honey if needed. Stir in the scallions and set aside. Reheat if needed before serving.
Slice the chicken and spoon the sauce over top. Serve with bread.
Notes
Pro tips: Butterfly the chicken: Lay the breasts down on a cutting board, using a sharp knife parallel to the cutting board slice the breasts through the middle (carefully) all the way in half.
