Well not all that hard, but darn good cheap eats.
I use a roasting pan which I cover the bottom with foil to avoid too much bottom heat. Turn the grill up high, which mine burns more on one side, so it would be medium on most peeps good grills. Cover it with a spice rub and bunches of home grown herbs. I collect all the drippings, strain, mix with milk, flour, and spices to make gravy. We pit it over rice, but sometimes use corn.
The leftovers are great. Chicken tacos, sammies, or soup. It is amazing how much you get out of a $5 chicken. Even made stock after the last one.
