I agree with most of the posters here. Even if the only animal products she eats are fish and eggs, when she reads the guidelines, she can just ignore all the meats w/legs. If her objection to eating meat, is killing mammals and birds, rather than using their byproducts, maybe she will eat milk products? In which case she can also add full fat yogurt and good cheeses to her protein arsenal.
Oils are easy: olive and avocado for example. Carbs are easy because she's already eating lots of plant products.
Grains and beans are out - remind her that over 85% of wheat, corn, and soy in the U.S. are GMO (she can check this with the USDA website for the exact numbers). Chances are if she's a veg/pescatarian, she doesn't want any GMOs anyway, so this will give her the out she needs to ditch the tofu.
I kind of like the idea of this in that I like the idea of all viewpoints being able to get healthy and eat real food.
