Sauté the pork until it takes on a golden color. Then, puree the onion and add it to the casserole.
Once the sautéing is complete, deglaze the meat with the wine and orange juice.
After the alcohol has evaporated, add the honey, cinnamon, nutmeg, salt, and pepper, along with a little water (about 1 glass), and let it simmer over medium heat with the lid on.
After approximately 60 minutes, add the prunes and continue cooking everything together for another 30–40 minutes over medium to low heat.
