Add olive oil, onion, and garlic to a large, high-sided skillet set over medium heat. Season with salt and black pepper, to taste, and cook, stirring frequently, until the onion and garlic softens and develops some color, approximately 3-4 minutes.
Season pork chops with sea salt and black pepper, to taste, and add to the skillet. Brown the chops on each side until they release easily from the skillet, approximately 4-5 minutes per side.
Add chicken broth, cannellini beans, and oregano to skillet. Season with salt and black pepper, to taste, and cover. Reduce heat to medium-low and cook for 8-10 minutes, or until internal temperature is just over 140°F with an instant read thermometer. Remove from heat, cover and let rest for 5 minutes.
While the chops rest, add the chopped escarole to the skillet and stir to combine. Sauté until just wilted, stirring frequently, approximately 2-3 minutes. Remove from heat and serve immediately with the pork chops. Enjoy!
Tip: The escarole in this recipe may be substituted with chopped kale, Swiss chard, or spinach.
