This recipe can be found if you search for it in the googlebooks version of Veganomicon (although how someone could be vegan and not own V'con is beyond me).
I saw a picture of these blintzes on someone's site, decided to try them, and bought the ingredients several weeks ago. Fortunately it takes a little while for potatoes and mushrooms to go bad because I kept putting off making them. Making my own crepes just seemed like such a daunting task! But lately I've been realizing that everything I think will be too hard actually ends up being pretty easy. Granted, these crepes were extra easy because I had my dad make the actual crepes (in a small, non-stick frying pan - who needs crepe pans?!) while I worked on the filling (I'm pretty sure I made the crepe batter too. I do things! Shut up!).
These were savory and held up very well during the couple of days they spent in the refrigerator. You could probably successfully reheat them in a microwave, but it only takes a couple of minutes to re-fry them. You don't even need to add any oil! I ate most of them smothered in applesauce, but for the picture I used sour cream (Follow Your Heart, I think) and some fresh chives.
