Since both of my tortoises are grazers (red-foot and sulcata) and I keep them in an outdoor pen, I don't use any tort diet. If you have a backyard i recommend taking yoru tort out to the grass (make sure its pestcide free) and letting him/her graze on the plants.

Commercial tort diet is usualy too high in protein. Depending on what tort you have, romaine lettuce may not even be heaslthy enough. Grass and hay is definitely the healthiest way to go, it promotes slow-steady growth and prevents pyramiding.
