I wouldn't see any problem with it. If she likes it, then more power to you. You might want to remove the onions from the Beef Consomme with Veggies, if it has any. Onions are really bad for dogs.
Another thing you can do is buy some packets of gravy mix (if you can find it in any shops near you), mix up a packet, and pour it over your dog's kibble.
Last year when all the canned dog food was being recalled in the States, I had some homemade beef stew up in the freezer that I fed my dog along with his dry food. He loved it. It had stew beef, potatoes, carrots (which he didn't like), peas, and I used cream of mushroom soup, cream of celery soup, beef broth, and a packet of onion soup mix. I cooked it all down in the crock pot (slow cooker), froze it in single-serving portions, and intended to eat it during the winter, but never did. I gave it to the dog because I couldn't afford anything else, and I was getting ready to move in a month anyway. It was perfect.
If you cook any meat, mainly bacon or sausage, save the grease. You can store it in a airtight metal container, like an old coffee can. When you feed you dog, add a tablespoon or two of the grease from the meat to her kibble.
