In a medium-sized bowl, mix mayonnaise, crab meat, lemon juice, Dijon mustard, Old Bay Seasoning, chives and Parsley.
Thoroughly combine all the ingredients and avoid breaking the crab meat too much.
Adjust the seasoning using salt, pepper and lime juice to your preference.
Cover and place the crab salad in the refrigerator for a minimum of 15 minutes to let the flavors meld together.
For a toasted bread, you can spread a little soft butter on one side of each slice.
Heat the pan over medium heat. Start toasting the bread slices with buttered side facing down, and cook until it is crunchy and golden brown. It may take around 2-3 minutes for each side.
Lay the bread on a clean surface.
Add lettuce on two slices. Top the salad with tomato slices and other toppings like avocado, pickles or cucumber.
Put the remaining slice of the bread on top to form a sandwich.
