That is what I'm finding cool about the pellet grill. You still have prep time but being as it's a constant temp cooking and convection... It takes less attention. No flame ups or need to turn the meat. I smoked ribs for nine hours last Saturday. I was working in the garden and couldn't help but put an eye on the ribs a few times. But, they needed no attention and I could have just as easily been at work or something.
All I need to do now is get my time/temps down. What I really need to work on is my lack of rub knowledge and cooking something besides steaks, chops, and burgers.
I have grilled a very boring past... very simple things in a very simple manner. I want to learn to cook all the things take a bit more time or more expertise.
