Heat a pot over medium-high heat, add a little olive oil, and sear the pork in batches, browning it well on all sides. Once it takes on a deep color, transfer to a bowl or plate and set aside.
In the same pot, add the onion, peppers, and carrots, along with some extra olive oil if needed. Sauté for 2-3 minutes.
Return the pork to the pot, add the thyme and mustard, and cook for 1 more minute.
Deglaze with white wine and, once the alcohol evaporates, pour in the vegetable broth, orange juice, and add the halved oranges. Season with salt and pepper, then simmer for 40-45 minutes until the meat becomes tender.
Remove the pot from the heat, stir in the honey, and serve the dish warm.
