Pre-heat oven to 200°C.
In a mixing bowl, add the brown granulated sweetener, balsamic vinegar, lime juice, ginger, garlic, and fresh chilli. Mix.
Add the cumin, paprika, oregano, onion salt, cayenne pepper, coriander, and the salt and pepper. Mix well.
Place the pork into the marinade and leave for 15-20 minutes.
Spray a lidded, ovenproof frying pan with low calorie cooking spray and set on a medium heat. Add the pork, reserving most of the marinade in the mixing bowl.
Cook the pork for 5 minutes sealing on all sides, then place into the oven with the rest of the marinade. Cover with the lid.
Cook for 15 minutes, then remove the lid and cook for a further 5 minutes.
Remove the pork from the pan and let it rest for 5 minutes before serving. Serve with some of the cooked marinade drizzled over the top and garnish with the wedges of lime.
