Cut the onions into thick slices so the rings stay firm and can hold the egg filling. Remove the center carefully so the sides do not break. Use the removed onion pieces by chopping them finely and mixing them with the eggs. Cook over low or medium heat so the omelet sets without burning. Turn carefully with two spatulas to keep the shape.
