Cook French fries according to package instructions while steak is marinating.
In a large skillet over medium-high heat, saute steak, peppers and onions until vegetables are tender and steak is cooked to your liking. Separate steak mixture into 8 equal portions while in the skillet, and top each portion with cheese. Cover and set aside to let cheese melt.
