Arrange a rack medium-high in the oven, preheat the oven to 375 degrees F, and gather all your ingredients.
Line an oven tray with baking parchment paper and place the eggplant slices in an even layer. Carefully brush the olive oil on both sides of the slices and sprinkle some kosher salt on top. Bake the eggplant, on the prepared rack, for 20 to 25 minutes. The eggplant should be darker in color – anywhere from yellow to brown, and slightly soft to the touch.
While the eggplant is cooking, you’re going to prepare a simple Israeli salad. Combine the cucumber, tomatoes, onion, parsley, and lemon juice in a medium-sized bowl. Mix well, adding salt and pepper to taste.
Slice the top of each pita bread (less than ½ inch) and open the pocket. Smear 2 tablespoons of the hummus across one of the interior sides; this is going to act as a base as you build the sandwich.
When the eggplant has cooled slightly, place 3 to 4 eggplant slices on top of the hummus, followed by a few slices of pickles and a layer of egg. Then, using a slotted spoon, add in some of the prepared salad, but be careful not to add the liquid from the salad or the sandwich will get soggy.
Drizzle the sandwiches with tahini to your liking and serve the Sabich with a generous number of napkins!
