No it won’t but the vegies will most likely go mushy. To avoid that add the vegie soup about an hour before it’s ready.
So fry your meat (no need to flour) add to the pot, add mushrooms, add cream of mushroom soup, add water or the liquid from the veg soup or stock to just cover the meat. Let cook. An hour before it’s ready add the vegies from the soup.
All you need to ask yourself is: Do I like cream of mushroom soup? And if the answer is yes go ahead and do it.
It wont clash with the vegtable soup?
