Prepare the lamb: cut and squeeze lime juice over the lamb and wash/rinse well with water. Drain well, pat dry and place lamb in a bowl.
Season the lamb with the green seasoning, parsley, onion, garlic, paprika and salt. Set aside.
Add the lamb and 2 cups of water to a pressure cooker. Cover and bring up to pressure; cook for 30 minutes.
Make the guava sauce: preheat oven to 350 degrees F. In a deep bowl, mix together hot lamb or vegetable stock, salt, garlic, nutmeg, parsley, thyme, pepper sauce, tomato paste and guava cheese. Mix well with a fork until the guava cheese melts completely. Set aside.
Place chops side by side in a deep baking dish (such as a 9 x 13 Pyrex or casserole dish). Spread guava mixture on top of lamb and sprinkle with chadon beni.
Bake 20 minutes or until the topping caramelizes. Remove from oven and let rest for 15 minutes before serving.
If you do not have a pressure cooker, you can cook the lamb in a Dutch oven or a heavy-bottomed pot with a tight lid. The cooking time will be longer, as will be the amount of water needed to cook the lamb. Add 4 cups of water, cover and bring to a boil, then reduce heat and simmer. When the lamb is tender, drain off any remaining liquid and reserve it to use in place of the stock to make the guava sauce.
Use your favourite brand of guava cheese if you cannot find Tricopilia.
