Use 2 water pans in the roaster to make sure that you capture as much heat as possible. Insert BBQ racks with cast iron griddles over the other 2 spaces. 1 water pan could be used as a hot hold for items you are just warming or to hold items when cooked. Use the 2nd water pan with an insert to make scrambled eggs.
Spray with non stick cooking spray and add your beaten eggs. Close the lid and wait till the eggs start to coagulate. When the liquid eggs begin to start resembling scrambled, mix thoroughly every 5 mins until the desired texture is reached. Doing it this way you can make scrambled eggs for a large group.
Bacon, Sausage, potatoes and pancakes:
Grease the griddle plates and cook directly on the griddle Sausages and larger items like chops and chicken pieces can be cooked directly on the BBQ racks but will take a little longer to cook than on a solid griddle plate.
To prevent scrambled eggs turning grey use a non stick or ceramic insert in the water pan. Available from your local restaurant supply retailer Purchase cast iron griddle plates from you local retailer (approximate dimensions 18” x 10” ) to fit onto your barbecue racks
Remember for optimum cooking keep out of the wind and when possible keep the doors in place.
