In a small bowl, add mayo, sweet chili sauce, rice vinegar, sriracha, and agave.
Then stir until well until you have a creamy sauce. You can give it a little taste and add more sriracha for a spicier sauce. You can also give it a shake of salt or garlic powder for added flavor.
Serve as a dipping sauce or drizzle it over bang bang cauliflower, bang bang tofu, or bang bang broccoli. It's great over rice and noodles too.
Notes
Feel free to leave out the agave nectar; I find it is sweet enough with just the sweetness from the sweet chili sauce and seasoned rice vinegar.
Add more sriracha if desired. I like my Bang Bang sauce a little spicier.
