I did a quick check and it seems like beef and chicken have a lot more protein per 100 calories than blackberries, lentils or any of the super foods mentioned earlier. The main weakness of these foods become apparent when looking at the complete lack of dietary fibers.
Sorry, vegetables: Specifically green leafy stuff. As distinct from fruits, nuts, seeds, legumes.
Full fat cow meat has between about 100 - 125 grams of protein per 2k calories.

Like that.
Whereas Kale has 175 grams of protein per 2k calories.
That's the kind of veggie I'm talking about.
Lentils have 155 grams of protein per 2k calories (lots of carbs too).
Soy beans are 164 (lots of fat).
Tempeh (which is soy cultured with a fungi) has 198 grams of protein per 2k calories.
And that's a whole cultured plant/fungus food -- the fungus has eaten some of the calories and made some extra protein for you.
Lean meat is another matter; the more fat that has been painstakingly cut off it, the higher the protein per calorie.
That's not a "whole food" though, and people don't really even like extremely lean meat.
Lean beef can be 217 grams of protein per 2k calorie, maybe more.
Tofu is 213.
Mustard greens are 215 (so close!).
It's hard to beat when you cut out all of the fat, because it's not as easy to cut the carbohydrates out of vegetables.
Textured vegetable protein (which is defatted soybean), is 300.
If the butcher gets to carefully cut the fat off the meat, I think we get to defat the soybeans too, right?
And it's high in fiber, unlike the meat.
If you wanted a whole food, like with tempeh, if you cultured the mustard greens with lactofermentation (bacteria rather than fungus), they should eat some of those calories and push the greens over lean meat as well. (Confirmed with one source, 222 grams of protein per 2k calories).
But microorganisms are better.
Spirulina is 400 grams of protein per 2k calories. (Bam!)
And in terms of fungi, nutritional yeast is a whopping 356.
Of course, there are also other reasons to prefer the vegetables to the meat, one of which is the type of protein (the high methionine).
