Cook peas: Add about 4 cups of water to a large pot and bring to a boil. Add the frozen peas and cook until just tender, this should take about 3 minutes. Use a slotted spoon or a strainer to remove peas and transfer them into a large bowl.
Cook rice: Using the same boiling water, add rice and cook until tender, about 15 minutes. Drain rice, return to the pot, and cover to keep warm.
Make dressing: In a small bowl whisk together the lemon juice, oil, salt and pepper.
Combine ingredients: Add the Hemp Hearts, cooked rice, beans, raisins, scallions, parsley, lemon zest, and dressing to the large bowl and stir gently to mix.
Serve: Serve warm or cold with extra scallions, parsley and Hemp Hearts as a garnish.
