Every 100 kcal of melba toast brings 3.1 g of protein. On that measure it ranks 65th of the 111 grains in this database and 619th of all 796 foods on the site. Measured by weight instead, its 12.1 g per 100 g ranks 21st in its group.
Around 12% of the calories in melba toast come from protein, so it is more of an energy food than a protein food. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
Weight for weight, melba toast has 3.8 g of protein for each gram of fat (12.1 g against 3.2 g per 100 g).
Set against barley flour, another grain entry in the database, a serving carries about 0.5 g less protein (barley flour has 3.9 g per 1/4 cup).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving quoted here is measured by weight at 28.4 g, and it covers about 7% of the 50 g FDA Daily Value for protein.
