Veggie or Kosher variants of last night's dinner

I have a lot of vegetarian and kosher friends, so I was thinking about how to do the recipe differently to accommodate them.

My first idea was to make a cannellini bean purée. And use that instead of the meat and yogurt. I would food process cooked or canned cannellini beans, drain them of any water so it has similar consistency as hummus. I would add olive oil, lemon juice, salt and pepper to taste. Then I would layer that first on the toasted bread, followed by cilantro, the eggplant, then tomato and I would finish it with nice cheese crumble like feta, or grated pecorino Romano.

For any kosher keepers, I would not make the recipe with meat and leave out the yogurt. The yogurt is really what cinches the whole thing together. I would also not substitute soy yogurt. One could try making a thin hummus and top it with paprika instead of cayenne. But don't just do the meat, it will be way to boring! And don't even think about substituting with mayo!
