Some plants go through a life-cycle where they change dramatically from one cycle to the next. Take wheat for instance. Wheat starts out as a green grass. If harvested at the right time, it can be considered a green leafy vegetable. Green beans are similar. Green beans are immature beans that have not "gone to seed" yet. Eating the immature bean is not the same as eating the fully mature beans. Peas are mature beans (seeds) and should probably be eaten infrequently in small quantities. (Although I do love pea soup with smoked ham hock).
As far as what Grok ate, I think it would mostly be small game, rodents, insects, fish, fruit, tubers and the occasional wooly mammoth.
Side note but if domesticated plants are off the table should domesticated beef be off the table as well?
