Wash and drain the meat. Pound the meat pieces with a meat mallet a few times.
In a medium-sized mixing bowl add the meat, pepper, and salt. Rub together well so that the meat is nicely coated.
Heat oil on medium heat in a wok or broad skillet.
Add the meat, pepper, and salt. Sauté the meat until it has a nice glaze. Do not brown it.
Add 2 cups of water, cover, and cook till almost done. Approximately 30-35 minutes.
Add additional water if it is drying out while cooking. Test the meat with a fork or skewer. The meat should be tender and almost done. Turn off the heat.
Uncover the meat and arrange a layer of the sliced potatoes on top.
Now add a layer of the sliced onions. You will need at least half a cup of water remaining. If not, add an additional half a cup of water to the meat to cook the potatoes.
Cover and cook on medium-low heat for 10-15 minutes until the potatoes are done.
Stir a couple of times carefully during cooking to ensure the meat is not sticking to the bottom of the pan and the potatoes are not overcooked.
Serve the pepper fry with pepper water and rice.
You can use it in a wrap or a main dish with salad and bread.
