“When school starts on Sept. 3, students in Portland in grades pre-k to 5th grade will find a vegan hot lunch option every day in the cafeteria at the district’s 10 elementary schools. Choices include vegan burgers, falafel, and kung pao tofu. The vegan options replace the cold vegetarian lunches that had been offered since 2011.”
