Remove the grates and open any vents. Pile in the charcoals and arrange across the barrel. Carefully squirt lighter fluid all over the unlit charcoal and let it sit for 10 minutes or so (Please follow directions on the can before applying lighter fluid if you've never used lighter fluid). Light the charcoals with a match and when the flame dies down put the grill grates back on. Place your vegetables on top of the grill grates then close the lid. Adjust the vents to reach a temperature of 250°F (the target temperature is 250°F; however, the temperature will fluctuate with the opening and closing of the lid, so a temperature between 240°F and 250°F is good).
