Salad dressing. Help Please?

I'm looking for unique salad dressings I'm trying to eat healthier more salads and sandwiches for lunch. But honestly the usual Ranch is getting old I would like to change it up with something a little more gourmet. Anything that's different I tried a Clic Cesar the other day that was good it's on my shopping list. Can you guys recommend anything? Store bought or any home made recipes. I would love something with mango or something nutty or anything that's different I’m not greatly concerned about the amount of calories it has, I just want it to taste good so that I don’t get bored with my salads. Oh anything that has a international feel t it would eb awesome too. liek i've had an Asian Sesame that's on my shopping list too and the Creamy cilantro dressing from Pollo Loco Awesome. Please Help. Thank's. ;D
