Bring a pot of water to a boil. Add the frozen peas and cover. Cook for 2–3 minutes, just until the peas are bright green and tender. Avoid overcooking to keep their vibrant color.
300 g frozen green peas
Drain the peas well. Add them to a food processor or high-speed blender with the tahini, lemon juice, garlic powder, lemon zest, parsley (if using), and a pinch each of salt and pepper.
