Add oil to a pot of boiling salted water. Add the macaroni and cook according to the directions in the package. (This took the longest time for me - around 15-20 minutes. Keep checking every couple of minutes past the 10 minute mark. You don't want your macaroni mushed from over cooking.)
In a wok, melt butter and add the flour and over medium heat, stir it for 5 minutes. Add milk and cook it for 2-3 minutes until the sauce has thickened. Turn off the gas. Add cheese,salt and pepper and mix well.
Add the cooked macaroni and stir well.
Serve hot and garnished it with cheese.
