Season the chicken on both sides well with salt and pepper.
Heat an oven safe nonstick pan or skillet on medium heat. Once hot, add the oil and butter. Saute the garlic to golden brown. Then cook the chicken on both sides to an internal temperature of 160 degrees. Once done, remove from the heat and add the broth to the pan to deglaze it.
Preheat the broiler on high.
Fan out the plum slices on the chicken. Place under the broiler for 1 to 2 minutes to get golden brown coloring.
Drizzle with balsamic glaze. Serve with bread. Garnish with microgreens.
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 to create two equal halves.
