How do you make a tomato soup with noodles?

honestly, you have to just try it. add 3/4 cup water first, and let it boil while you whisk it for a little bit. after its all even, taste it. if you like it thicker, add more tomato sauce and a little more water. if its too thick, add a little more water. also, adding chicken broth instead of water makes it taste SOO much better, and im sure your father in law uses it. if you dont have it, use chicken boullion cubes/powder. then, when the broth is done, boil water and cook the pasta according to package directions, but take a minute or two off the cooking. so if it says 10 min, only cook it for 8. then strain it and add the noodles into the soup, and boil for another min or 2. hope it helps
