In a large pot on the stove add a few tbsp of oil, salt and pepper and brown the stew meat on medium heat. Next add 4 cups of water and the carrots and turn heat up to high. Boil until carrots start to get soft. In the meantime peel and quarter the potatoes. Keep them large so they do not fall apart in the stew. Add 3 more cups of water and the potatoes and onions. Boil until potatoes get soft. Add two more cups of water. Add the three gravy packets to 1/4 cup of water in a cup and stir. Pour into pot. Turn heat down to low. Simmer for about 5-10 minutes. Add more salt and pepper if needed.
