First, add the egg, mayonnaise, Dijon, hot sauce, Tony's, and pepper into a large bowl and mix well.
Second, in a separate bowl, combine the crab, Panko bread crumbs, and parsley and mix well.
Third, add the mayonnaise mixture and the crab mixture together and combine well.
Next, using your hands, form the creamy crab mixture into 10 mini crab cakes and place them onto a plastic cutting board, a baking sheet lined with parchment paper, or a plate to rest while the oil heats up to fry them.
Then, take a large skillet or a non-stick pan and heat the vegetable oil over medium heat.
Pan-fry the mini Cajun crab cakes in two batches of 5 so that the pan doesn't get overcrowded.
Fry the mini Cajun crab cakes for 4-5 minutes on one side, then flip them over and cook another 3-4 minutes on the other side.
Whenever the mini crab cakes are golden brown on both sides, take them out of the skillet and place them onto a paper towel-lined wooden cutting board or plate.
