Tons of people showed up ... Kourtney Kardashian, Orlando Bloom, Anthony Kiedis, Robin Thicke, Sofia Richie, Larsa Pippen, Caitlyn Jenner, Adam Sandler, Simon Cowell and Gerard Butler.

The cook-off pits anyone who's up for it to put their chili talents on the line ... a panel of judges decides which bowl is most worthy ... and which bowls aren't.

It's really more like a carnival, with lots of rides for the kids. Simon brought his son and protege, 4-year-old Eric. Kourtney brought her kids as well.

Normies who show up can get up close and personal with celebs, most of who seemed up for taking selfies.
