This was a very good idea! What I did was I diced up 1 raw chicken breast, sauteed it in 1-2 tbsp oil with minced garlic, garlic salt, oregano and fresh rosemary. As the chicken finished up cooking I added the onion and carrot (not a celery fan) and sauteed it for a few more minutes. Then I added the broth, waited for it to boil and put in the rice. I put in a lot more cumin and pepper than the recipe called for. It turned out excellent!
This soup was just OK for me. My hubby really liked it, but I didn't care for the flavor that the peas added to the broth. (I don't care for peas in casseroles for the same reason, and should have known better.) I downsized the recipe to only 3 servings without a problem, and added the peas and the lemon juice suggested in the intro. It was easy to prepare.
