With the screenwriters' strike over, Eva Longoria-Parker is returning to Wisteria Lane – and getting back in shape.

"We're back and it's like we never left," Longoria-Parker told PEOPLE Saturday afternoon in Los Angeles while accepting a donation for the children's cancer charity, Padres Contra El Cancer. "We were such a well-oiled machine before we broke so the stop was jolting."

Having dismissed pregnancy rumors in January by pointing to her strike-induced indulging, the Desperate Housewives star is back to her work health regiment.

"I'm working out, I'm eating my healthy food I get prepared," she said with a sigh. "It is so much easier being in shape when you're on the show because you have a chef and the gym is right there, so you really have no excuse."

Fresh off a plane from San Antonio, and heading to catch a plane to New York, quality time with husband Tony Parker may be limited, but the actress is still in honeymoon mode.

"We've only been married seven months so I hope the spice is alive on its own!" she laughed.

Along with her work on the show, Longoria-Parker has another project: her new Latin restaurant Beso opens in Los Angeles on Thursday.
