Atlanta schools are putting vegetables and other non-meaty foods front and center in school lunches today in recognition of Earth Day.

Nearly every Atlanta school will serve only vegetarian lunches today, including black bean and corn quesadillas in elementary schools, baked buffalo cauliflower in middle schools and black bean burgers and garden vegetable pizzas in high schools.

It’s part of a partnership with the Humane Society of the United States to promote “plant-based” foods as part of a healthy diet and environmental conservation, according to the Humane Society.

Atlanta schools already generally offer at least one meat-free option daily, and have branched out in recent years, offering students kale smoothies and sushi.
