My mistake, I had blindly dismissed rice since it is commonly known to be a nutrient poor food. But several sources confirm the parent post and your comment are correct*. It's also too often repeated that a vegetable based diets will be lacking essential amino acids which seems like a gross falsehood now if you can get there with two wildly available plants that make up a common low-cost meal. I am baffled by the disconnect.

*I don't cite the source since I am unsure if there are caveats or if the claim is controversial.
