Heat the olive oil in a large frying pan over medium-high heat. Add the pork in a single layer and brown well on all sides. Do not overcrowd the pan; work in batches if needed. Fry 3 minutes first side, before flipping, 2 minutes on the other side. Use a splatter guard if you have one as this can get a little messy!
700 grams boneless pork shoulder, 4 tbsp Greek olive oil
With the pork still in the frying pan (if you seared it in batches, return all the pork to the pan now), add the onion and cook until softened and lightly golden. This will take about 4 - 5 minutes. Stir occasionally to prevent burning. Add the garlic and cook for a minute or so until fragrant.
1 large onion, sliced, 2 cloves garlic, thinly sliced
Pour in the white wine and let it simmer for 2–3 minutes, scraping up the browned bits from the bottom of the pan.
1/2 cup dry white wine
Next add the sliced peppers, season with salt, pepper, oregano and paprika. Stir, and lower heat to medium-low, cover loosely, and cook for about 20 minutes, stirring occasionally, until the pork is tender and the peppers are soft but not mushy.
3 bell peppers, assorted colours, sliced, 1 tsp dried oregano, 1 tsp salt, 1/2 tsp pepper, 1 tsp sweet paprika
Uncover, increase heat slightly to reduce any excess liquid if needed. Add the lemon juice and mustard and mix well. Taste and adjust seasoning if needed, to your taste.
juice of 1/2 lemon, 1 tsp yellow mustard
Sprinkle with fresh parsley and serve immediately.
