The Asian/Vietnamese truck by the Biology building, off Main Street and near Kendall - in search of a healthy lunch yesterday I ordered the papaya salad and it far exceeded my expectations. A big serving with shredded papaya, red onion, cilantro, ground peanuts and your choice of chicken or tofu. I went for chicken - moist shreds, seasoned with salt and pepper. The salad comes pre-dressed plus a side of rice (not necessary) all for $4. I will go back.
