What do I search for when looking for unsweetened recipes?
As pointed out in the comments, the correct search term is "savory."  Keep in mind, however, that while chefs often create savory versions of typically sweetened items, those versions usually have sugar or other sweeteners in them.  In granola, for example, we understand it generally as a sweet breakfast or snack item.  While the sweetness in the savory version is dramatically reduced, it is that remaining sweetness that allows us to interpret it as granola.  Otherwise, it would just be toasted grains, which, maybe in the end, is what you want.
