Lay out bacon slices on a parchment-lined sheet tray. Generously brush each slice with Frank’s Red Hot Original. Bake for 15–20 minutes, until bacon is browned and cooked through. Drain bacon on a paper towel, keeping the hot sauce brushed side facing up. Set aside.
3. Step
Place a large piece of plastic wrap on a large cutting board (the entire board should be covered with plastic). Place 1 slice of bread in the upper left corner of the board. Brush the right edge of the bread with whisked egg, then place a second slice of bread next to the first so that it overlaps with the egg wash. Press the two seams of bread together with fingers to seal. Repeat with the rest of the bread, forming 3 rows of 4 slices, brushing with egg wash and pressing to seal wherever the slices overlap. This will form a large rectangle of bread.
4. Step
Use a rolling pin to roll out the bread rectangle as thinly as possible.
5. Step
In the center of the rectangle, lay out half of the chicken in a row. Top with a drizzle of ranch dressing. Arrange half of the bacon slices on top (horizontally),followed by half of the sliced cheese and half of the spinach. Repeat layering with the rest of the ingredients.
6. Step
Brush the top edge of the sandwich roll with whisked egg. Roll the entire sandwich up from the bottom to form a long log. Wrap log tightly with plastic wrap. Refrigerate for 30 minutes.
7. Step
Lower oven temperature to 350ºF.
8. Step
Mix together melted butter and ranch in a small bowl. Unwrap the sandwich log, place on a sheet tray, and brush sandwich surface with ranch butter.
9. Step
Bake for 18–20 minutes, until bread is lightly golden and cheese is melted.
10. Step
Slice and serve. (Optional: Serve with more ranch for dipping.)
