Start with boiling water for the tortellini then once boiling cook tortellini.

While that's working, in a medium bowl add the imitation crab meat, onion (sliced), fresh mozzarella (cut into 1/2" cubes), olive oil, the zest from one lime along with the juice from both (depending on the size), & the vinegar.

Drain the tortellini & place in an ice bath the drain when cold. WAIT! Do not add the tortellini yet! Mix the contents of the bowl thoroughly first, NOW add the tortellini (don't want to break the tortellini by mixing it too much).

Add the parsley (chopped), the scallions (sliced), & the salt & pepper to taste. Now give it one last mix gently being careful not to break the tortellini & you are done!

I don't normally use measurements when I cook; therefore the measurements provided are a close approximation for a good neutral flavor. Some people like more, others like less, so use your own judgment on how you want your dish to taste & make whatever adjustments you need.

Enjoy!
