For one, my eggplants were way too small. Even though I cut back on the amount of filling, there was a lot of it left over after I stuffed my little purpling darlings. For two, there was bit too much going on in the filling. Next time I might cut back on the number of vegetable types involved, and let just a couple of them shine a bit more. The feta, on the other hand, was an excellent inclusion. I could have used more of it than I did.
All told, a qualified keeper.
