I doubled the recipe but felt it needed one more egg for the double batch. Probably depends on the bread crumbs, plus I used smaller eggs. This were still great warmed up in the microwave. Just added a squeeze of fresh lemon before adding a dollop of sauce.
I especially loved the sauce and felt the yogurt makes it even better. I'm considering baking up a batch and then freezing them, thinking they could be thawed in the microwave, then finished up in a skillet. Maybe mini ones on a toothpick with the sauce would make a good appetizer as well.
