Measure and prepare all the ingredients.
In a mortar, crush the minced garlic, parsley, salt, and pepper together.
Mix the seasonings with the olive oil and coat the chicken breasts on both sides.

Preheat the grill. If there are any leftover bits from previous grilling, let it burn off for a while.
Wipe the grill with a cloth to clean it. Once the grill is very hot, place the chicken on to cook. If using a charcoal or gas grill, make sure to keep a safe distance so the chicken doesn't burn.

I made this recipe with fresh garlic, but I actually prefer using garlic powder. Fresh garlic can burn easily on the grill and turn bitter. Most of my grilled recipes use garlic powder—it's safer.
Serve with marinara tomato sauce.

I use a gas grill with lava rocks.
