Boil the potatoes in salty water. After 20 minutes, check them with a fork. If they are not tender enough, cook them for 5-10 minutes more.
Drain and let them cool for about 10 minutes. Chop them into bite-size pieces.
Meanwhile boil green lentils in another pot for 15-20 minutes or until tender. Drain and pour cold water over them to help them cool.
Throw the fresh peas in boiling water and cook for 3 minutes or so. Don’t overcook them, otherwise they lose their nice green color. Transfer the cooked peas into cold water to stop their cooking and drain.
In a large bowl, combine chopped potatoes, green lentils, peas, green apples, green onions, parsley and dill pickles.
To make the tahini dressing:
Combine all of the ingredients in a food processor and blend until completely smooth. Taste and make any adjustments you like.
Drizzle the tahini dressing over the salad and give it a good stir. Serve it at room temperature.
