Fire up your stove with a soup pot on high or set your Instant Pot to saute until the oil is ready to cook your onions and garlic.
Add garlic and onion and saute until fragrant.
Add carrots and celery and saute 4-6 minutes.
Add broth, chicken, potatoes/turnips, broccoli/cruciferous veggies, italian seasoning. Set instant pot for 7 mins on high pressure. Or cook medium / low heat on stove until fork goes through the carrots and taters. A lid will help but if you don't have one don't worry about it.
Release the pressure on the instant pot and add your greens and pasta or rice. I like to just leave it warming with the soup til it's ready to serve and the grains plump up all nice and take up space. You could cook them separately if you don't like that and combine them when serving the soup. For stove top preparation just add the pasta and cook based on the package directions (on the al dente side cuz it'll keep softening in the broth). For rice I would plop the grains in there with the greens and let them simmer for about 10 minutes, longer for brown rice.
Add salt and pepper to taste and optional parmesan! Leave it out if you want dairy free. I'm sensitive to dairy but parmesan doesn't bother my sinuses in small amounts. YUM YUM IN MY TUM TUM.
