Buy these for your grill: http://www.grillgrate.com/
A) In a foil packet, assemble a mixture of white and red onions, some sort of pale ale, butter, and mustard. Let that packet on the grill for 20 minutes, foil packet completely closed.
B) Once the surface temperature of the grillgrates are up to 400 degrees, throw on your brats (I'd recommend Queen city hot and spicy, Schmidts Bahama Mama's, or anything from the Bucyrus Ohio Area) and grill until the internal temp is 135 degrees. The grates give you the perfect infrared cook, with perfect grill marks, and no bonfire brat effect.
Add A to B, and wash down with at least two beers.
