A typical 1 cup cooked serving of frozen green peas contains 8.2 grams of protein (5.15 g per 100 g), which makes it a good source of protein. That covers roughly 16% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 26% of the calories in frozen green peas 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, frozen green peas ranks 2nd by protein per serving, and 344th out of all 796 foods on the site. Set against scalloped potatoes, another vegetable entry in the database, a serving carries about 1.2 g more protein (scalloped potatoes has 7 g per 1 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 above is measured by volume at 160 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
Peas are one of the higher-protein vegetables, but the amino acid mix is incomplete on its own.
