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 great source of protein, a single cup of tofu contains 20 grams of protein, or about 40% of recommended daily values. [1]
To get the adequate amount of protein with tofu alone, you will need 2.5 cups of tofu (620 grams) for an average female, or 3 cups of tofu for males. [4] That's about 470 calories.

Tofu contains abundant amounts of 8 out of the nine essential amino acids. Proportionally, tofu is a little short on methionine.[1]
To have adequate amounts of all nine essential amino acids with tofu alone, you will have to eat 3.2 cups of tofu (796 grams) for an average person. [2]
That's about 28% more tofu to compensate for the lack of methionine, compared to the protein requirement alone.
