Slice pretzel bites in half and place on a baking sheet - cut side up. Drizzle with half of the olive oil and place under the broiler for 2-3 minutes or until golden brown. Remove from heat and set aside.

Meanwhile, get a large skillet heated over medium-high and create little clumps of mortadella with each slice. Add the remaining olive oil then add the clumps of mortadella.

Fry for a few minutes on each side until golden and crispy. Top each one with a tiny piece of provolone cheese and then stack two of the cheesy meat piles on top of each other. You will probably need to do this in 3-4 batches.

Smear the bottom of each pretzel bite with the dijonnaise then top with a pile of the cheesy crispy meat then put the top of the slider on top.

Repeat for all pretzel bites before serving.
