A couple years ago I was trying to learn more about the paleo diet and came upon someone's blog. The guy was from India and wanted to reconcile paleo with Indian cuisine. What he concluded was that if he looked at what his grandparents and great grandparents ate, there wasn't quite as much naan and roti as the current diet contains. He realized the diet of his grandparents was far healthier than today's diet. More rich buttery gravies, more vegetables, less wheat (might have been none at all, I don't remember) and certainly no candy, pastries or other processed foods. He figured if his family just went back in time that far with their diet they'd be ahead of the game. I don't remember if he was a vegetarian or not, I know he wasn't a pure vegetarian, but you are neither so you may find this easier than you think if you just look at it differently.
