Trim fat off Roast, in a large pot put Roast, Green Beans, both cans of Soup. Add water until it's about 2" over meat, bring to boil for 20-30 minutes, stirring occasionally to mix everything well. Then reduce heat to medium heat, you want it to slowly boil adding more water if it gets too low. Cook for 3-4 hours.
Mean while peel and cut potatoes in cubes, place in a bowl of cold water until ready to use, after your roast, soup and beans have been cooking for 3-4 hours put your potatoes in the pot.
Let it all cook together about another hour or so until the meat and potatoes are very tender and liquid has cooked down and somewhat thickened. To make the yummy juice from the roast, soup and veggies cooking you can add alittle flour in and stir. Remember to stir occasionally throughout the whole time. When ready turn heat off let sit for about 20 minutes, salt and pepper to taste, serve over rice or wide noodles and a roll.....YUMMY. Even better if you have left over a the next day.....ENJOY
