One way to add in fat w/out protein is to make smoothies made w/ coconut milk. Fruit and coconut milk, and you could make them 'green smoothies' adding greens to them as well. You can also make coconut oil bark (cocoa powder mixed w/ coconut oil--= parts I think, plus honey or stevia or no sweetener depending on what you like. You could add nuts as well.)
Just a couple of ideas!
