The sabich sandwich is an amazing Israeli invention that marries fried eggplant, potatoes, hard-boiled egg and pickles! Add a few vegetables, slather on the tahini sauce and add some spice; you've got the perfect eggplant sandwich.
Arrange the eggplant slices neatly on the baking sheet, ensuring none are covered by other slices. Drizzle with olive oil and sprinkle with salt and pepper. Roast eggplant in the oven for 15-20 minutes.
While the eggplant is cooking, peel and cook the potatoes. You can use the microwave approach or cook them the old-fashioned way, in a pot of water. Slice boiled potatoes.
Mix the tahini paste with water in a small bowl, add a pinch of salt, and whisk together until creamy and blended together. When ready to assemble the sandwiches, cut open the pita bread horizontally.
Layer and add ingredients to the pita. Follow with a layer of alternating cucumber slices and tomato slices. Top with onion slices and pickle slices. Add a layer of sliced boiled eggs.
Drizzle the tahini sauce on top of all the ingredients. If you like spice, spread harissa inside the last bread slice, or drizzle with your favorite hot sauce.
