Melt 1 tablespoon butter in a large skillet over medium-high heat.
When pan is hot and a drop of water sizzles when added to the pan, add the chunks of steak.

When butter stops foaming, add cauliflower and cook for about 2 minutes, stirring occasionally. Add onion to the pan and cook until edges of the onion are just starting to brown, then stir in the peppers. Season with salt and pepper,
When peppers are crisp-tender and onions and cauliflower are tender and cooked through, stir in steak cubes and any liquid that has collected. Stir in parsley just before serving.
