Amanda Seyfried and Josh Hartnett Sample Snacks at Farmers' Market
Harnett, in a black sweatshirt, and Seyfried, in a black sleeveless tee, stopped by the Mediterranean stand, taking particular interest in the hummus.
"The sampled items from the stand and made a purchase," an onlooker tells PEOPLE. "Then they hit the strawberry stand and grabbed a three-pack. There was no PDA but they seemed like they were happy."
