Lightly dust your work surface with flour. Spread the crescent rolls out and gently cut along the perforated lines, creating a total of 8 rectangles of dough, each of which is made up of 2 connected triangles. Be careful not to disconnect them.
Evenly spread 1 teaspoon of Dijon on a rectangle of dough. Top with one slice of cheese and one slice of turkey. Gently roll the short edge of the dough rectangle into itself and continue to roll like a burrito. Once the roll-up meets the last edge of dough, gently pinch together to create a seal. Repeat this step with the remaining dough.
Gently lay the roll-ups seam-side down in the baskets. Sprinkle tops of roll-ups with sesame seeds, if desired.
Insert both baskets in unit. Select Zone 1, select BAKE, set temperature to 325°F, and set time to 30 minutes. Select MATCH COOK to match Zone 2 settings with Zone 1. Press the START/PAUSE button to begin cooking.
When the time reaches 5 minutes, press the START/PAUSE button to pause cooking. Remove baskets and flip roll-ups so the bottom sides are facing up. Reinsert basket and press START/PAUSE to resume cooking.
When cooking is complete, remove roll-ups from baskets and serve with more mustard or other desired condiments.
