Yes. In Jain dharma, tomatoes are generally allowed as they are not root vegetables. Most Jains avoid root vegetables (like onion, garlic, potatoes) but tomatoes and other non-root items used in meals or snacks are commonly considered acceptable.

If you follow a strict vrat or a specific tradition (Digambar vs. Shwetambar) you might have slight differences in practice, so you can check with your guru or reference your community guidelines for any local variations.

If you’d like, I can summarize the basic Jain dietary guidelines (ahimsa, non-violence, and avoiding root vegetables) in simple terms or tailor the guidance to your specific tradition.
