Bring a large pot of water to boil and season with salt, lemon, bay leave, peppercorns, and garlic.
Once boiling, poach the fish in batches: Scallops (about 2 minutes); Calamari (about 2-3 minutes); Shrimp (about 2-3 minutes or until pink); Lobster (about 5-7 minutes)
As each fish is done, transfer to an ice bath to stop the cooking process, then set aside on a paper towel lined baking sheet to dry.
Prep the dressing by combining the parsley, shallot, red pepper flakes, and EVOO in a small bowl. Season with salt and mix until fully combined.
Then thinly slice the fennel, chop the olives, and dice the roasted pepper.
Transfer the fish to a bowl, add the fennel, olives, roasted peppers, and dressing. Mix until fully combined. Then taste and adjust salt, pepper, and lemon to taste.
