Place all ingredients in a high speed blender. Process until smooth. (Start with a 1/4 cup of water first and depending on your blender, gradually add a little bit of water at a time until smooth. I used about 1/2 cup of water)
Scoop into a tray / container and freeze for 2 hours or until desired texture is reached. Allow to defrost a couple of minutes before enjoying.
Serve with some more tajin seasoning sprinkled on top!
