Cook pasta according to package directions. While the pasta is cooking, cook longaniza on medium-low heat until cooked through but not crispy. Set aside to cool.
When the pasta is done, drain and rinse with cold water. Mix cilantro dressing and pasta together until all the dressing has been absorbed by the pasta.
Slice tomatoes in half, cut green onions into thin circle slices and add to the pasta along with the cooked longaniza. Stir well. Season with salt to your taste.
This salad can be made in advance, just remember to keep it in the fridge until you're ready to bring it out to serve. It can be served immediately, or straight out of the fridge. Either way, it's good!
