I want to take the DC on a tour of SE Asia (Vietnam, Laos, Thailand, etc.) as our one big holiday before before they hit the teenage indifference stage. However 3 of us are vegetarians and I remember from my travels in the 90s that meat free was somewhat a challenge between the ubiquitous fish sauce everywhere pork central in Vietnam. Have things moved on since then are we going to starve for 3 weeks?
