Travellers with sensitive stomachs, what did you eat in Thailand?

Thailand is known for its street food culture but my experience with that hasn’t been great. I remember I got really sick from a halal food cart in NYC and I’ve been cautious about that ever since. I’ve only travelled to places with little to no street food presence since but I will be heading to Southeast Asia later this year. I would love to some tips for Thailand or other countries like Vietnam and Laos
