Using a biscuit cutter, cut 8-10 circles out of the pie crust (if your package contains 2 pie crusts, feel free to make a few batches of these empanadas and use all the dough!)

Using a butter knife spread a little bit of mustard onto one half of a circle of dough (don't spread it all the way to the edge), then add a little bit of ham, then add a cheese pieces, then a few pickle slices.

Fold the dough over to cover the fillings and using a fork press/crimp the edges of the empanada together so that no gaps remain (you don't want the filling oozing out).

Spray the basket of your air fryer with cooking spray. Put empanadas into the basket and spray empanadas with a little bit of cooking spray (don't over-crowd the basket, depending on how big your air fryer is you might have to cook the empanadas in batches). Cook for 8 minutes, flipping empanadas halfway through. Remove from air fryer with tongs and then enjoy!
