"It’s somewhat well-known that the amino acid profile of grains complements the amino acid profile of legumes. The reason why grains are not considered a whole protein is because one of their amino acids is lower than the rest."
This is false information.
While it might be true for certain grains, check out the distribution of essential amino acids in quinoa. You will see that you get everything you need:

Other grains vary. Buckwheat (kashi) is as good as quinoa:

Not all grains are as good as quinoa and buckwheat, to be sure. Rye is very good, but not quite 100%:

However, assuming you eat some foods other than rye that day, it is a very good bet that you will be safe.
Brown rice is also relatively good, but not as perfect as buckwheat or quinoa:

And, since beans have lots of protein with very little fat, it is ideal to eat both grains and beans if you want to make sure you get a large amount of protein (as I do, since I lift weights).
However, many vegetables will give you sufficient protein as well, in addition to filling in the missing amino acids in brown rice and rye. There is a common myth that vegetables lack sufficient protein. Not true - unless you eat only potatoes, or some other ridiculous diet.
Check out how much protein broccoli has, and how it has all of the essential amino acids:
http://nutritiondata.self.com/facts/vegetables-and-vegetable-products/2357/2
If you ate 2000 calories worth of broccoli in a day, you would get 140 grams of protein. Unless you are a body-builder and weigh 100+ kg, this is enough for people who lift weights to add muscle mass, let alone those who don't to survive. When I work out, I try to get 1.5 grams of protein per kilo of body weight, based on various sources, in order to put on muscle. That means that eating pure broccoli would be enough for someone on a 2000-calorie diet (too few for most men) who weighed 85 kilos to add muscle mass. Most body-builders I have known eat more than 2000 calories, however. If you ate 2500 calories of broccoli, you would get 175 grams of protein. That is a LOT!
Asparagus also has an ideal amount and proportion of amino acids:

If you ate 2000 calories worth of asparagus, you would get 200 grams of protein. This is probably far too much for most people.
Now for a different example: a veggie low in protein. Sweet potatoes have all essential amino acids, though one (lysine) is slightly lower than the optimal amount (easily made up as long as you eat some broccoli, or asparagus, or buckwheat, etc. etc.). They don't have so much protein, however - if you ate 2000 calories of sweet potatoes, you would only get around 40 grams of protein a day (which is arguably enough for most people, unless they are actively trying to build muscle, and may not be enough for growing kids).

Still, who would eat only sweet potatoes?
The point is that you can get lots of protein from eating veggies. Enough, even, to add muscle mass.
The protein myth is exposed by John Robbins in his book "Diet for a New America". He says that the meat and dairy industries are the source of the myth.
You do not need to eat meat, or animal products, to get sufficient protein. You do not need to even combine grains and beans.
(If you are actively trying to add muscle mass, though, it is probably not a bad idea.)
The reason that beans are so desirable is that they have loads of protein, and loads of fiber as well, and are low in fat.
Meat, on the other had, has loads of protein, no fiber, and lots of fat.
Even notice that fiber and cholesterol are in complementary distribution? I mean that all animal foods have cholesterol, and zero fiber, and all plant foods have fiber, and zero cholesterol.
As for a vegan diet being healthy - that was my reason for adopting such a diet.
I sometimes get a craving for fried chicken, and go for it, but I try to eat vegan foods 95% of the time.
I do not care for the religious zeal of some vegans, and I dislike labels, so I hesitate to call myself "a vegan".
(Plus there is the issue of that fried chicken 8) )
However, it is clear to me that a plant-based diet is by far the healthiest diet.
