In a large skillet over medium high heat, add your butter and let it melt part way.
While butter is melting, wash the cauliflower and cut into bite sized pieces.
Once butter is melted part way, add in your cauliflower and stir.
Add in garlic powder, salt and pepper and mix well.
Cook until the cauliflower is tender and starts to get a little bit of the brown coloring from being cooked with butter. While cauliflower is cooking, cut steak into bite sized pieces.
Once cauliflower is tender add in your steak bites and heavy cream and mix well. Cook until your steak is your desired doneness.
