I can't say for sure, but catering menu includes a couple of Italian pastas in addition to other picnic standards and finger foods.
The stand's other options are just a jumbo dog (also Vienna) for $3.50 and chips and cookies as sides. The current location Monday-Friday is mid-campus at the corner of West Johnson and Charter Streets, a zone without many places to lunch. The cart's also visited other spots, so check for location at its calendar.
