Eva Longoria Parker may play a desperate housewife on TV, but the actress is not afraid to put on an apron for a good cause in real life.

Longoria Parker donated a catered dinner – and some tableside service of her own – for an auction to raise money for the New York Rescue Workers Detox Project at her restaurant Beso in Hollywood on Thursday.

During the live auction, she hopped up onstage to encourage the audience, including stars such as Bradley Cooper, to bid on her donated in-home dinner for 12 courtesy of Beso. Then she decided to throw in a personal appearance, in which she'll wear an apron and make tableside guacamole. As if it needed anything more, she sweetened the deal by including two tickets to a Spurs/Lakers playoff game, and a Tony Parker jersey. The package sold for $37,500.

Event co-hosts Danny Masterson, Leah Remini, and Terry Seymour – along with guests Simon Cowell, Wilmer Valderrama, and Poppy Montgomery – also pledged money to the project, which aids 9/11 rescue workers affected by the toxins at Ground Zero.

"You know what? This is an easy thing to do," Cowell told PEOPLE of the evening. "The guys we are raising the money for, they do the hard work."
