Crush the garlic and add the seasoning along with the olive oil and massage into the cutlet.
Put the chicken into the refrigerator for a few hours.
Before grilling, take the chicken out of the refrigerator and allow it to come to room temperature.
Place the chicken on a heated grill and close for 2 minutes or so. You must learn how your grill works - some grills get hotter than others - and some have hot spots. A bit of practice will make perfect.
I like to turn the breast 90 degrees to get cross grill marks - which looks very professional. Cook another minute and then flip.
Repeat the 90-degree turn so both sides look great.
The chicken is done when it is cooked through - which again - takes a bit of practice. Word of advice - most people overcook chicken breast. You want it just cooked through - it will continue to cook when you take it off the grill.
A meat thermometer should read 155 - and when you remove it - it will rise to 160 - which is the recommended cooking temperature for chicken.
Let it rest five minutes before serving.
