Turn your broiler / grill on to heat.
Scatter the peas over, then pour the egg over top, and allow to cook until the egg is just about set, which should be about 5 minutes. Crumble the cheese over top, and transfer the pan to under your broiler / grill. Grill for 2 to 3 minutes or until the top is golden. Serve hot.
