Stir together all the products for the marinade.
Make 3/4″ (2 cm) wide cuts in the meat but not all the way through, in order to make it like a fan. Smear it all over with the marinade, sprinkle with spices. Cover with foil and put in the fridge for 4-5 hours, best if overnight.
Chop the processed cheese, cheese and bacon into pieces, as many as the cuts on the meat. Take the meat out of the marinade.
I chopped the processed cheese into thin round slices and put 3 in each cut. Put bacon in between the processed cheese and cheese.
Pour the marinade on top, cover with aluminum foil and put to bake in a preheated 392°F (200 °C) oven. Bake at this temperature for 30 min., then lower to 356°F (180 °C) for 1 hour.
Uncover the foil and leave to crisp on top.
Notes: You can strain the released sauce and serve it with the meat. I didn't add salt because it takes in plenty from the soy sauce, processed cheese and cheese.
