Bring an inch of water to a boil in a large saucepan fitted with a steamer basket.

Add potato wedges to the steamer basket.

Cover the saucepan and steam the potatoes for 10 minutes.

Place chopped broccoli florets on top of the potatoes in the steamer basket.

Cover again and steam until both the potatoes and broccoli are tender, approximately 6-8 minutes more.

Transfer the steamed broccoli to a large bowl.

Coarsely mash the broccoli using a potato masher.

Add the steamed potatoes, shredded Fontina cheese, heated nonfat milk, salt, and pepper to the bowl.

Continue mashing all ingredients together until you reach your desired consistency.

Taste the mash and adjust seasoning with more salt or pepper if needed.

Serve the Cheesy Broccoli-Potato Mash immediately while hot.
