Lay out a warm tortilla and spread a thin layer of Dijon mustard over the surface, covering it evenly.
Place 2 slices of turkey on the mustard-covered tortilla, spreading them out to cover most of the surface, leaving a small border around the edges.
Add a few slices of cheese on top of the turkey, aiming for even coverage to ensure melty goodness inside.
Sprinkle chopped herbs over the cheese for a fresh flavor boost, and add crunch elements if desired for extra texture.
Carefully roll up the tortilla from one end to the other, pressing gently to keep the filling inside and creating a tight wrap.
Preheat your pan over medium heat until it feels warm and starts to emit a gentle sizzle.
Place the rolled-up tortilla seam side down in the hot pan, pressing lightly with a spatula for even contact.
Cook for about 2-3 minutes on each side, until the exterior is golden brown and crispy, and the cheese inside is beginning to melt.
Use tongs or a spatula to flip the roll-ups carefully, ensuring even browning and melting.
Once golden and crispy, remove the roll-ups from the pan and let them rest for about 2 minutes to set the cheese.
Slice each roll-up into 1-inch pieces with a sharp knife, revealing the gooey cheese and layered turkey inside.
Serve warm, garnished with extra herbs if desired, and enjoy the crispy, cheesy, savory bites.
