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.
Relatively low in protein, a single cup of cornmeal contains 11.8 grams of protein, or about 24% of recommended daily values. [1]
To get the adequate amount of protein with cornmeal alone, you will need 4.2 cups of cornmeal (510 grams) for an average female, or 5.1 cups of cornmeal for males. [4] That's over 1950 calories. Pairing cornmeal with a richer protein source is a good idea.

Proportionally, cornmeal does contain abundant amounts of 7 out of the nine essential amino acids. However, cornmeal is a little short on lysine and tryptophan.[1]
To have adequate amounts of all nine essential amino acids with cornmeal alone, you will have to eat 4.7 cups of cornmeal (568 grams) for an average person. [2]
That's about 11% more cornmeal to compensate for the lack of lysine and tryptophan, compared to the protein requirement alone.
