EMILY: How is your Caesar salad dressing prepared?
LUKE: I’ll have to call Paul Newman and ask him.
Luke is saying he doesn’t make his own salad dressing, he is using a bottle of Newman’s Own dressing, a brand of condiments and foods founded by Hollywood star Paul Newman and author A.E. Hotchner in 1982. The company, headquartered in Westport, Connecticut, donates 100% of its after-tax profits to the Newman’s Own Foundation, a private non-profit foundation which supports various charitable causes – one of them is the SeriousFun Children’s Network, residential summer camps for seriously ill children all over the world, which Newman co-founded in 1988.
