In a large bowl, mix together the Surimi Flakes, mayonnaise, celery, tarragon, green onion, garlic, lemon juice, mustard and olive oil until well combined.
Cover and refrigerate for at least 1 hour.
To serve, spoon a generous 1/3 cup of the crab mixture into each roll. Serve in hoagie roll, on bread, or with an avocado!
Garnish with parsley, if desired. (Can be made the day before and chilled overnight)
