In a large bowl add your chopped scallions and parsley along with mustard, mayo, sriracha, old bay, and the juice of one lemon.
Gently pick through the crabmeat looking for any pieces of shell. Try to not break up the lumps as best you can.
Finally, fold together all the ingredients so that the crab meat is well coated. Let chill in the refrigerator for 30 minutes before serving.
Sliders
To prepare the sliders brush melted butter on your rolls then lightly dust with old bay and toast under the broiler for about 2 minutes. Keep a close eye on them to make sure the rolls don't burn.
Pile the crab salad on top then add a layer of lettuce, tomato, or pickles if you like before cutting it into individual sandwiches.
Notes
Serving size one slider sandwich with about 2-3 oz of crab salad.Store crab salad in an airtight container. Use within 48 hours once opened.
