A typical 1/4 cup serving of sun-dried tomatoes contains 1.9 grams of protein (14.1 g per 100 g), which makes it only a minor source of protein. That covers roughly 4% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 22% of the calories in sun-dried tomatoes come from protein, so it is moderately protein-dense. 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.
Among the 105 vegetables in the database, sun-dried tomatoes ranks 55th by protein per serving, and 660th out of all 796 foods on the site. Set against green beans, another vegetable entry in the database, a serving carries about 0.5 g less protein (green beans has 2.4 g per 1 cup cooked).
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 above is measured by volume at 13.5 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
Drying concentrates everything, so the protein per gram is far above that of a fresh tomato.
