A perfect dish to share is baked vegan pasta. Pick your favorite organic pasta, make your organic sauce from scratch, and add your favorite cheese substitute.
Personally I like to make my ricotta out of tofu, crumbled and seasoned as my relations traditionally seasoned ricotta. The only difference is what I am seasoning, tofu instead of sickening cow cheese (dairy allergy).
For the topping, I usually do not use fake vegan cheese, but this is what my relatives are used to seeing, so I use it for them.
