I use both Zoo Med Grassland Tortoise Diet and Mazuri Tortoise Diet (not the LS). I put a few kibbles of each along with a few kibbles of alfalfa pellets into a small container and add too much water then cover the container and put it in the fridge overnight. The next morning all the pellets have absorbed the water and are ready to mash up with a fork. After I've got them all mashed and broken down into less than crumbs I toss them into the greens making sure they are well distributed and are no clumps. If your tortoise won't eat it this way, then use less pellets. You have to get him used to the smell of them, and it may mean starting out very small - only one or two pellets.
