First, skin, & bone the breasts.
Next, I like to brine chicken especially if I'm going to grill it.
You can find a good brine recipe online... Since you like it spicier, I suggest adding either crushed pepper flakes, or pepper paste to the brine. Be careful though, a good rule of thumb, when spicing up a brine, is to use about half as much spice as you would in a dry rub.
I keep this seasoning mix on hand, I'll give you the quantities just remember you WILL have left over mix after you make your chicken.
2 cups each:
Basil, Oregano, Thyme, Parsley.
1/3rd cup each:
Salt, Cracked Pepper, Crushed red pepper, cumin, garlic powder, onion powder.
1/4 cup cinnamon
2 Table spoons nutmeg.
Mix all together
I like to make a Bleu Cheese Beurre Blanc sauce to go with this, so, here's a link to a basic sauce recipe...at the very end, add like a half cup of crumbled Bleu Cheese:
Beurre Blanc RecipeNext, melt about a half pound of BUTTER, gotta be butter... let it cool to room temperature.
Coat the chicken with the butter.
Cover the bottom of a plate, or pour a good amount of the seasoning mix into a large bowl, and after coating the chicken in the butter, toss the chicken well in the seasoning mix to thoroughly coat the chicken.
Next, on a HOT grill, place the chicken Skin side down, and cook for about 2 minutes. Turn, and cook an additional 1.5-2 minutes, or until you get an internal temp of 170degF.
Serve with a rice mix, pasta, or a mash, with whatever is in season around you, grilled veg.
Top with some of the Bleu Cheese Cream Sauce.
Enjoy.
