Step 1

Preheat oven to 350 degrees F.

Step 2

Cook frozen cauliflower per bag directions. Drain and mash the cauliflower then add 1/4 cup of the sour cream and 1/2 cup of the shredded cheddar. Mix well and taste to see if you need additional salt/pepper and add to your taste. Set aside.

Step 3

Brown ground beef and onion in a large skillet; drain fat and place in a large bowl. Add the remaining sour cream, shredded cheese and broccoli florets.

Step 4

Turn the meat mixture into a small (1-1 1/2 quart) casserole, spreading evenly over the bottom. Top with the cauliflower mixture, again spreading evenly to cover. Sprinkle Parmesan cheese over the top.

Step 5

Bake for 30-40 minutes or until heated through and cauliflower topping begins to brown.
