Every 100 kcal of dinner roll brings 3.5 g of protein. On that measure it ranks 44th of the 111 grains in this database and 574th of all 796 foods on the site. Measured by weight instead, its 10.9 g per 100 g ranks 27th in its group.
Around 14% of the calories in dinner roll 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, dinner roll has 1.7 g of protein for each gram of fat (10.9 g against 6.47 g per 100 g).
Set against all-purpose flour, another grain entry in the database, a serving carries about 0.5 g less protein (all-purpose flour has 3.2 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 counted by piece at 25 g, and it covers about 5% of the 50 g FDA Daily Value for protein.

Sample figures for one made-up week against a 110 g goal, not your data. Red bars met the goal. Your own log fills this in with Premium.
10.9 g. The 1 roll serving used on this page weighs 25 g and so carries 2.7 g.
How much protein do you get per 100 calories of dinner roll?
3.5 g. That figure divides its 10.9 g of protein per 100 g by its 310 kcal per 100 g, so it does not depend on serving size.
Is the protein in dinner roll complete?
No. On its own, the protein in dinner roll is short of at least one essential amino acid; other protein sources across the day fill the gap.
What share of the protein Daily Value is one serving of dinner roll?
About 5%. One 1 roll serving has 2.7 g, and the FDA Daily Value for protein is 50 g.
