I'll do a couple, bottom up -

Tyrosine, usually biosynthesized, from substances abundantly found in soy.

Proline - whole cabbage family works just fine.

Glycine - none-essential, as it can be synthesized from basic elements.

Glutamine - non-essential.

Cysteine - common, synthesized under normal conditions, otherwise.

Arginine - Beans, nuts, etc..

 

Again, the human body is very good at creating what it needs, most of those can be produced, and are produced under normal circumstances by the metabolism to fit needs.

 

What concerns proteins alone, Soybeans, Quinoa, Chia, Buckwheat, and a couple others contain sufficient amounts of the *essential* amino acids that they are, by themselves, enough to fill the needs, if eaten as sole protein source.

Heh starting from the bottom was a mistake because those were the non essential proteins or conditionally essential.

The essential proteins are more important, because the body can't naturally make it. If you could list easily accessible foods for the essentials, then maybe it would be possible.

Soybeans are great and have all essential amino acids in tofu and stuff but they are not all equal proteins. For example they are low in Methionine and Cystine which, unless you eat excessive amounts, you won't get it from soybeans alone. Quinoa is much worse on protein side, so I don't really consider it so viable. Chia same story as Soybeans. Buckwheat same as Quinoa. So while possible, is not feasible in my opinion.

T bone steak, chicken, turkey heck even fish only needs a small serving to solve all your protein needs for an average person. The problem is compounded for people with a larger need for protein.

Looking it up, apparently certain essentials are considered complementary, apparently, so only containing one or the other is sufficient to let it be considered "complementary."

Those 2 can be found in other food without too much of a stretch, however, methionine in nuts/grasses (wheat, etc...) and cystine in the cabbage family.

 

As stated, it's of course much easier for a vegetarian to fill these dietary needs (eggs have just about everything and then some...), so that's probably what should be recommended, from a nutritional perspective.
