I'm always looking for alternatives to mayo when it comes to salads. I've used Greek yogurt and even guacamole to great success, but smoked mashed eggplant pulp is really where it's at when it comes to binding ingredients. 

This super-simple smoked eggplant fingerling potato salad recipe is great for cookouts because while you've got the grill fired up, you can toss a couple of eggplant halves on there, forget about them for a while, then remember them, think you burned them and discover that underneath that dark layer of char is savory velvety-smooth smoked eggplant ready to blanket your potatoes. Serve this easy-to-prepare side with any grilled fare you like — chicken, fish, steak or simply alongside other summer vegetable dishes.
