You gotta eyeball all the seasonings, cheese, etc, so good luck
Cook 1.5 cups white rice. Cook it in low sodium chicken broth for more flavor, but not required!
Cut raw chicken into bite size pieces and cook with oil/butter, salt, pepper, and Italian seasoning. Set aside.
Cook onions in butter. Set aside.
Microwave 2 bags of Steamfresh broccoli florets and drain off any excess water.
In a large bowl, combine 1 can cream of chicken soup, 1/2 cup milk, 1/2 cup sour cream, 2 tbsp mayo, the onions, 1 small can mushrooms (drained), a couple handfuls of shredded cheddar cheese, salt, pepper, garlic powder, and ground thyme.
Grease a 9x13 baking dish. Dump in the rice, broccoli, chicken, and all the mixture in the bowl. Fold until well combined. Top with more cheese.
Bake at 350F for 35 minutes or until cheese is browned. Boom.
