I mean I have. There are almost no vegetables that are considered amino acid complete though there are (well known) combinations like legumes (beans/lentils) + rice. But this goes back to my original point of needing a lot of beans to get your protein requirement for the day. In places like India where there are a lot of vegetarians, diary products are heavily used to make up the deficit.

This is just blatantly and hilariously false.
They are literally called "essential amino acids".
A plant would not survive if it lacked amino acids which are essential.
It it shocking anyone would deny this obvious and extremely basic fact about biology.
