Need Recipe for boneless lion roast on the bab-b-q

Hi everyone, first I want to thank everyone her for all the wonderful recipes you have posted and I have tried with DH as Guinea Pig.

We are hosting a church group and different members seem to have specialties that they serve, but none have pork. I was able to pick up three wonderful beautiful full pork loins for a steal. I usually cut them up for porkchops but I was thinking of this get together and was wondering if there was a way to do them on the barby.

Thanks for any help
A
