It wouldn't be too hard to convert it to vegan. Im sure as a vegan you are very used to adapting meals to your needs. What I would do. is try to stick to the Macro counts on the program and try to get 30/40/30 so the port/fat portion should be easy enough its 30/30 so beans and lentils will be your best friend here. and the 40 is just the carbs so fruits and veggies and bam your done. it will be a metric ton of food though sticking to good clean vegan food.
