Buttermilk Sour Cream Oat Sourdough Tangzhong Rolls

I have made sourdough rolls using the Tangzhong method before and they usually come out great. I decide to change it up a bit and used buttermilk instead of cream or milk and added some sour cream for an added flavor boost. I also added some fresh parmesan cheese and used rolled oats, white rye and spelt flour to try to make it a little healthy.
I have to say when these were baking the whole house smelled amazing.
