Blanch the pako
Bring a pot of water to a boil.
Add the pako and blanch for 30–60 seconds.
Drain and immediately rinse with cold water or place in ice water.
Drain well.
Prepare the dressing
Mix vinegar, calamansi juice, sugar (if using), and black pepper in a small bowl.
Assemble the salad
Combine the pako, tomatoes, and onions in a large bowl.
Pour the dressing over and toss gently.
Add the salted eggs
Arrange the salted egg pieces on top or gently fold them in.
Serve
Let sit for 5–10 minutes before serving so the flavors meld.
