There's a misunderstanding about grilling that it take time. Yes, it does if you do the conventional way. Using self igniting charcoal makes the world different how much time you want to spent at the grill.

Marinate your meat, veges in the morning before you go to work. After you come back, throw in those self igniting charcoal, throw in a match, it lights up. NO BLOWING, NO need to pour gas fluid. Come back to it after a while and the charcoal are red hot. Throw in your meat and the veggies.

Grilling can be tedious or simple. You pick.
