As my oil was heating in the pot, Kirby and I chopped carrots and celery. We decided we didn't want to put the full 14 ounces of both vegetables in our pot, so we didn't. That's the beauty of cooking your own meals. If you don't want as much of an ingredient as a recipe calls for, change it or even omit it if you want! Once chopped, we threw the carrots, celery, and pre-chopped frozen onions in the pot to sweat. I also added a couple tablespoons flour at this point, because several reviews mentioned the broth being quite soupy.
