Anything to fix rolls? Or clever ways to reuse them somehow?

I am usually able to convert just about any recipe to a vegan version. Last night I did "Hawaiian rolls" (using a whole wheat bread flour instead of a white flour) and the original recipe called for them to be brushed with egg and honey, so I used coconut oil and agave nectar instead. When the rolls first came out of the oven they were delicious and just about perfect. This morning the whole bottoms feel kind of soggy (the tops do not). I'm not sure if it's because I used oil instead of egg or something else gone wrong? Any ideas on how to salvage them? Or use them in some other way? I hate wasting food.
