Combine the just egg, mayo, mustard, Old Bay, Worcestershire, celery and parsley, and salt in a large bowl. With a rubber spatula, gently fold in the artichoke, hearts of palm, and panko. Mix until just combined.
Shape into 6 patties (about ⅓ cup each.) Place on the baking sheet and chill for 1 hour to help them set. You can speed this up to just 10 minutes in the freezer, just be sure to give it a stir every few minutes so it chills evenly.
Airfry:
Airfry the crab cakes at 375F for 20 minutes, flipping halfway through.
Fry:
Preheat a large nonstick pan over medium high heat and fill with ½”-1” (1.25-2.5 cm) of oil. When the oil is hot, add the cakes to the pan. Cook for 3-5 minutes on each side, until crispy and golden brown.
Slice the slider buns in half. Layer the buns with a crab cake patty, arugula, tomato slice, and vegan mayo. Serve and enjoy!
