Spinach: Spinach is relatively high in protein for a leafy green vegetable. It contains about 2.9 grams of protein per 100 grams when cooked.
Broccoli: Broccoli is another vegetable with a decent protein content. It has around 2.8 grams of protein per 100 grams when cooked.
Peas: Green peas are a good source of protein among vegetables, containing approximately 5.4 grams of protein per 100 grams when cooked.
Kale: Kale, similar to spinach, is relatively protein-rich among leafy greens, with about 2.9 grams of protein per 100 grams when cooked.
Brussels Sprouts: Brussels sprouts contain around 3.4 grams of protein per 100 grams when cooked.

Remember that the protein content of vegetables can vary depending on factors like cooking method and freshness.
