Procedure
FIRST: Sous vide process the Butternut squash as explained HERE.
After processing at 183 F/84 C for one hour, submerge the squash in iced tap water until it achieves 70 F/21 C. Refrigerate at 40 F/4 C until day of service. Remove the squash from the pouch carefully and pat dry with a paper towel. 
Cut into desired shapes, approximately 0.75"/2 cm thick. Save the trim for other applications like Butternut squash gnocchi or Butternut squash tortellini. Place the individual steaks on a paper towel. 
Fold the paper towel over each steak. 
Wrap in a fabric kitchen towel and vacuum in a sous vide pouch. 
Remove the towel, and then the paper towel. 
Dust lightly with powdered egg white. 
Mist lightly with water. 
Apply desired seasonings. 
Spray or drizzle lightly with vegetable oil. Set aside. Preheat plates in an oven set on "warm," approximately 170 F/76 C. 
Make the popcorn as per the package directions. Set aside. 
Preheat a small skillet to 275 F/135 C, add a few drops of oil and add the peanuts. This light browning process only takes a few seconds. Stage the peanuts to a paper towel and sprinkle lightly with kosher salt, garlic powder and paprika. Set aside. Wipe the skillet dry with a kitchen towel. Return the skillet to the burner and heat to 275 F/135 C. Add a few drops of vegetable oil and sear each squash steak--do not crowd the pan. This process takes about 30 seconds for each stake. Turn the steak over and continue searing for another thirty seconds. The steak will have an internal temperature of at least 140 F/60 C. Stage each steak onto a plate. 
Drizzle the balsamic syrup around the steaks. Arrange the popcorn and peanuts around the steaks as shown. Place a piece of the blue cheese and a peanut on top of each steak. Place a small piece of the blue cheese on the plates as well. Dot the top of the cheese and steaks with the extra virgin olive oil. Place a few drops of the sambal olek on the plates and sprinkle with parsley or chopped mint.
