Get your vegetables cooking in a steamer or pot of boiling water.
Meanwhile, heat a little butter or olive oil in a frying pan, and fry your steak pieces over med-high heat until nicely browned.
Add garlic to the steak and stir, cooking for a further few minutes.
Once vegetables are cooked, strain the water out (if you boiled them) and add to the frying pan with the steak and garlic.
Add cream and cook over medium heat, stirring, until sauce thickens.
Turn off heat and add cheese, mixing until it has melted through the sauce.
Set aside to cool for a few minutes and then serve.
