Combine all the ingredients for the crust in a shallow bowl or plate and mix until well combined.
One at a time, place the chicken breasts in the seasonings and cover them well with the mixture. Turn them around a few times, pressing on the seasonings lightly with your fingers to help it adhere to the chicken and reserve.
Heat a few tablespoons of healthy cooking oil over medium high heat in a large oven-safe saute pan equipped with fitting lid; once the pan is hot enough, add the chicken breasts, 2 at a time, and sear for a minute or two on each side, just until a nice golden crust develops. Reserve to a plate and repeat with the remaining breasts.
Return the chicken to the skillet and arrange the pieces of lemon around the chicken. Put the lid on and bake in the oven for 25 minutes, then uncover and continue cooking for another 5 minutes, or until the lemons are slightly caramelized and the chicken looks nice and crispy.
Slice the chicken breasts and spoon some of the the delicious juices that accumulated at the bottom of the pan over the meat.
