PRINCETON — The cheesesteaks and cupcakes served out of food trucks in Princeton on Saturday will feed more than those who attend this year's Truckfest.

Sales from the food truck event, organized by members of Princeton University's eating clubs, will benefit Meals on Wheels of Trenton/Ewing and Mercer Street Friends' Send Hunger Packing program.

"We think it ties in very well," said Princeton junior Kate Gardner, co-chair of the event. "We identified hunger as a cause that we really care about and is incredibly important to us."

The event from 2 to 6 p.m. will feature a lineup of more than 15 trucks, including The Taco Truck that opened a fixed restaurant in the Princeton Shopping Center in December.

Gardner said she hopes the event, with the tagline "Eat the Street," raises at least $30,000 for the organizations. Prospect Avenue from Washington Road to Roper Lane will be closed to motorists on Saturday from 12:30 to 6:30 p.m.

Last year's gathering was the first of its kind for the eating clubs, with 11 trucks bringing in $22,000 for the Send Hunger Packing program that provides hundreds of low-income schoolchildren with meals to take home on the weekends.

"We are really excited as an organization to be expanding the event," Gardner said. "We have more of a focus this year on giving it a festival feel, as well as the increased food options and the goal of more funding for the charities, which we love."

Mercer Street Friends supplies more than 2.5 million pounds of food annually to more than 60 organizations in Mercer County, including Catholic Charities, HomeFront, the Rescue Mission of Trenton and the Trenton Area Soup Kitchen. Meals on Wheels delivers about 50,000 meals to more than 400 homebound residents every year.

Organized this year as the Community Service Interclub Council, a university group in charge of the food truck event identified a handful of possible charity partners, Gardner said. It chose the two organizations after an application process because of their efforts to address food insecurity.

The council visited both locations to see the each group's work in action, Gardner said.

"What these charities are doing really confirms their mission to fight hunger and our decision to partner with them," she said.

One of the problems last year was long lines. Each truck has been asked to offer three of their best menu items to help expedite the process, Gardner said.

Musical acts and street performances by Princeton students will be free. Access to the food trucks requires a $2 ticket.
