I think I know what you're referring to, it's pretty much the same as "gyros" (pronounced yee ros) ground lamb, beef and goat, seasoned and molded to go on a spit and then thinly sliced and served. I believe you Canucks call it "Donair". Someone at the Brethren site did one a few months ago, and it appeared to come out very well. I don't see why you could not do it as long as you get the traditional seasoning mixture right. You should give it a shot!
After further research, he used the Alton Brown recipe from www.foodnetwork.com
It looks to be a good recipe, he also put it on his bbq rotisserie. good luck
