To spread the love of summer flavors, Olivia’s Organics, Chelsea, Mass., has started a summer harvest recipe contest.

Recipes must include Olivia’s Organics greens and summer ingredients. They may be submitted on Olivia’s Facebook page by Aug. 30.

The winner will be chosen and notified by Sept. 10 and will receive a $500 Williams Sonoma gift certificate and recognition as the featured recipe on Olivia’s website. Everyone else will receive a coupon for a free sample of salad greens.

Although this is the first recipe contest Olivia’s has held in its four years, the company has been involved in many charities, including children’s hospitals, the Make-A-Wish Foundation and a scholarship for Camp Joslin for children with diabetes. Earlier this year, the company also held an Olivia look-alike contest at EarthFest in May, which went to Nora Flaherty.
