I made this soup for today's lunch. It was good, but I did modify the recipe, as seeing how the size (ounces) of the boxed hamburger helper has been reduced. To the (6.4-ounce) box, I only added 2-(14 ounce) cans of beef broth, instead of adding the 5 cups of water, plus I added the liquid from the canned corn, which then made 4 cups of broth/liquid. As for the onion, I just added 6 tablespoons of diced onion, which is a bit less than a medium sized onion. As for the corn, I added it when I added the zucchini, noodles, and just 1 teaspoon of the Italian seasoning, which I then brought the soup to a 2nd boil, then reduced the heat, covered the pan, and let the entire soup simmer for exactly 15 minutes, other wise the zucchini and noodles would of still been a bit undercooked. One more thing... I didn't have a can of Extra Hot Rotel Tomatoes. I only had the "Original" Rotel Tomatoes, so to add a bit more heat, I added some Tabasco to my bowl of soup. I forgot to top my bowl of soup with the parmesan cheese, and the soup still tasted good. For those who prefer a much milder tasting soup, I would suggest using the "Original" Rotel Tomatoes, but if you change your mind and want to make it a bit spicer, just add some Tabasco to your bowl of soup. This was very good soup, and I look forward to making it again. LILTEXQT... Thanx for the recipe!
