That's quite a sparse list, Walnuts have 3mg/100g (33% DV) [1] Sunflower seeds 5mg/100g (53% DV) [2] I'm currently holding a 340g bag of raw organic walnuts I opened this morning, and it's nearly empty just from snacking throughout the day. Also snacked on sunflower seeds, but not much. Dinner was a large bowl of lentils, which have 3.5mg/100g (35%) [3] Without even optimizing for it I'm over the RDI for Zinc without animal products, this is just what I happen to be stocked up on currently. So clearly it's not much of a challenge for a vegetarian to get sufficient Zinc.
