1. Remove cream cheese from package and start to soften it in a container that’s big enough to hold all the sauce ingredients. (You can partly soften cream cheese in the microwave if you need to.)

3. Bring a pot of salted water to a boil, add broccoli, and cook 3 minutes, or even slightly less.
4. After 3 minutes, immediately dump broccoli into a colander placed in the sink and let it drain well.
5. When the cream cheese is softened, mix in sour cream, 2 T coarsely grated Parmesan, 1 cup sharp cheddar, and sliced green onion. (Blogger FAIL, missed taking a photo of that.)
6. When broccoli is well drained, put it into a mixing bowl. (Pat dry with paper towels if it seems very wet.)

8. Add ham cubes and gently combine with the broccoli and sauce.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Ham and Broccoli Casserole is a great dish for low-carb diet plans. I am also tagging it Keto because this could be a one-dish meal. It could be adapted to be suitable for any phase of the original South Beach Diet by using lean ham and low-fat cheese and other dairy products (and maybe using a bit less cream cheese or substituting a more SBD friendly option.)
