Summary:
A complete protein is a protein source that "contains adequate proportions of the nine essential amino acids" that our body can not produce on its own.
A decent source of supplementary protein, a single cup of collard greens contains 1.1 grams of protein, or about 2% of recommended daily values. [1]
To get the adequate amount of protein with collard greens alone, you will need 46 cups of collard greens (1660 grams) for an average female, or 55 cups of collard greens for males. [4] That's about 530 calories, and a lot of collard green! Supplementing collard green with food higher in protein is a good idea.

Proportionally, collard green does contain abundant amounts of 5 out of the nine essential amino acids. However, collard green is a little short on leucine, lysine, methionine and phenylalanine.[1]
To have adequate amounts of all nine essential amino acids with collard green alone, you will have to eat 72 cups of collard greens (2606 grams) for an average person. [2]
That's about 57% more collard green to compensate for the lack of leucine, lysine, methionine and phenylalanine, compared to the protein requirement alone.
