Greek Lemon Grilled Chicken

Years ago my friend Perry told me how to marinate lamb and I have been doing it ever since.
All I had was chicken and I followed his recipe to make the most delicious meal.
I did change it a little.
8 to 10 pounds of bone in chicken thighs
Trim off any excess skin but leave a little
1/2 cup olive oil
1/2 cup lemon juice
zest of two lemons
6 cloves of diced garlic
One teaspoon garlic powder
Two heaping teaspoons salt
Two teaspoons corse ground pepper
4 teaspoons dried thyme
4 teaspoons dried rosemary
2 teaspoons dried oregano
Combine everything together
Pour over the chicken and rub into each piece
Marinate at least one day in the refrigerator.
Heat the grill to medium high
Place the thighs on the grill and close the top of the grill.
Cook for 8 to 10 minutes
Turn over
Cook for another 8 to ten minutes.
Cover with foil
Finish off in a preheated 425 degree oven for another 30 minutes
Have a feast with rice pilaf, yogurt sauce, fresh pita bread, olives and any vegetable you like.
A big fattoush salad would be perfect.
Thanks Perry
