Place peas and turkey leg into a pressure cooker. Stir in onion, garlic, olive oil, pepper, and water to cover. Bring to a simmer. Close and lock lid.
Adjust temperature until regulator is gently rocking. Cook at high pressure for 15 to 20 minutes. Let pressure release naturally according to manufacturer's instructions for at least 5 minutes; open lid and add more water if needed. Replace lid and cook until beans are tender, 5 to 15 minutes more. Let pressure cooker cool for about 5 minutes before opening. Remove turkey bone.
Depending upon the smokiness of the turkey, the taste may be different and spices may be adjusted to meet your individual tastes. If you want to make it vegetarian, just omit the meat and add your own seasonings. Cooking times and number of servings may vary.
To cool the pressure cooker quickly, run under cold water before opening.
