There's a giant head of broccoli at the very top of the new pyramid? They emphasize protein AND fresh produce.

I guess what I'm lamenting is the missed opportunity to highlight that many vegetables e.g. broccoli are an excellent protein source as well as other important nutrients. It gives you additional flexibility when meal planning. There's a common misconception (at least in my circles) that protein => animal protein which isn't always useful for planning a balanced meal.
Broccoli has 2.8g of protein per 100g. Beef has 26g per 100g, and chicken has 27g. If you're trying to get protein, broccoli isn't going to do much, and I think it's good that the government is being honest about that. A chart that listed broccoli as a major source of protein would be misleading. Broccoli is a good source of many nutrients, and the chart calls it out as such, but it is not an effective source of protein.
If you compare protein per kJ instead, broccoli has 0.021g protein per kJ whereas lean beef mince has 0.028g per kJ. Much more similar. Although of course you would need food that is higher density protein as well so you don't have too much volume to eat.

Normalising by mass is a poor way to assess food's protein content since different foods have greatly different water contents. E.g. beef jerky has much higher protein per 100g than beef largely because it's dried (admittedly, probably also because they use leaner cuts)
Good luck getting Americans eat sufficient broccoli to source their protein without also adding a ton of cheese or fat/sugar based sauces.

I can see why you would expect something like that from this administration, but surprisingly the linked webpage seems to be based in fact.
Broccoli are not an excellent protein source from a dietary perspective.
I like broccoli, but you’d have to eat around six pounds of broccoli to cover the recommended daily intake of essential amino acids.
It’s harder to get the target 1-1.6g protein per kg from vegetables, unless you’re consuming beans/pulses which are also high in carbohydrates. Broccoli is not a great protein source, an entire head will give you 10g at most – the average adult would have to eat a dozen+ per day.
Beans and pulses are mostly long chain carbohydrates, which are not a problem.
You have to consume a very large amount of lentils to make up a healthy amount of protein per day. It’s something like 6 cans of chickpeas vs two chicken breasts per day. I believe you also don’t get a complete amino acids panel like you would with meat which is complete on its own.
Indeed, chickpeas don't supply sufficient essential amino acids[1]. But sesame is[2] and goes well with chickpea! See falafel or hummus.

You can challenge beliefs and do a modicum of research, which would easily disprove this false and frankly ridiculous notion, which defies even a rudimentary understanding of plant biology.

Most protein rich vegetables are legumes and beyond this are also rich in complex carbs. Legumes are in the top 10 food allergies. Not to mention the amino profile of vegetable sources isn't very good.
those are terrible sources of protein.
