yes, a gas grill takes less effort. Same cooking instructins abd times. Ok, we grill at least 3 times a week even in the "winter" we do not really have winter.. Anyway momod2 is correct about the charcoal, but let me give you some other tips..
Before you place the coals down there, call up some newspaper, about 3 or 4 pieces.. then pile on the coals.. Try not to use lighter fluid if possible.. light the newspaper so the fire begins from the bottom of the pile.
Once the coals are grey and this can take a while (15 to 20 minutes)for them to get grey then spread them out and then place the grill on top.
place your hand over the grill (not on it) to get a feel of the heat It should feel hot to your hand in about 3 seconds.. This will be like "med" on your stove..
Then place your seasoned chicken parts (no BBQ sauce yet) or breast on the grill. Place the cover of the grill on top with the vents open.. DO NOT lift the lid, Do not flip the meat over and over.. Let the smaller pieces grill for about 8 min on each side and the thicker parts (breast with bone) for 10 to 12 minutes on each side. use tongs, not forks to turn over the pieces.. the juices will stay in the meat and keep it moist.
IF you want BBQ sauce on it, at about 2 minutes, before the chicken is ready, paint the chicken with the BBQ sauce on all sides. Then close the lid and let it grill for about 2 minutes.
If you do a boneless chicken breast you cook each side for about 6 minutes on each side,.
If you do steaks, it depends on the thickness and how well you want it cooked. We like med rare, so we cook a steak for about 6 minutes on each side for a 1 inch thick steak. (remember keep the lid closed and only turn it over once)
If you like it well done 10 minutes on each side should make you happy.
The other secret to grilling is to let the meat sit once it is cooked.. Place it on a platter and let it sit for at least 3 minutes. It will make a huge difference in the juiciness of the meat..
I hope this helps.. Wish I could be there to show you in person.. It takes reassurance that you do not lift the lid, do not poke and cut it while on the grill.. And it takes some practice to figure out when the coals are ready.
