Was told I could suggest things in the Vampirism Discord and finally found the place to do so, I don't use Github much so if I did this the wrong way my bad.

My suggestions include:
Wolfberry Icecream
Wolfberry Pie
Wolfberry Cookie
Wolfberry Muffin
Smoked Liver
Liver Sandwich
Cracked Bone Broth
Only other ideas are dishes made entirely of meat or human flesh

I'll consider most of those, but Wolf Berry Ice Cream and Cookie are already a thing. Though there's a constant problem with adding any kind of food made out of Liver or Human Heart. Their food values are simply huge themselves, and the food made of them would be way too saturated, so I don't see much sense in it. Smoked Liver may be added though.
