Hamburgers, steak, chicken breasts, grilled vegetables and any other main course meal can be prepared on an outdoor grill. These units are all powered by propane gas and vary in size from single tank units that resemble the barbeques found in homes across the country to ones that are hauled around on their own trailer. The size of the outdoor grill you need depends largely on the client size and intended application. Small kitchens that will not grill that often should only need a single tank unit. Caterers and large resorts or golf courses will need a grill that has multiple propane tanks and at least eight burners. Those who want to set up a grill at a trail head or football stadium parking lot should opt for the grills that come on a trailer and hitch to the back of a truck. Each grill comes with a water pan that goes below the burners. Rather than dripping onto the burners and causing flare-ups, grease drips into the water trays. This also facilitates easy grill cleaning.
