Shred and finely chop the imitation crab meat into small pieces using a knife. Place it in a large mixing bowl.
Step 2: Add Shrimp
Add the salad shrimp to the bowl. If the shrimp are large, chop them into smaller pieces.
Step 3: Mix the Filling
Add mayonnaise, Mrs. Dash seasoning, black pepper, salt, and lemon juice (if using). Mix everything thoroughly until creamy and well combined.
Step 4: Chill the Mixture
Cover the bowl and refrigerate for at least 1½ hours. This step helps the flavors blend together and improves the texture.

Step 7: Add Vegetables
