Midnight Snack Mac N Cheese

Ok, I made it at 6 pm, but then I ate it again at midnight...

Mac N Cheese
1 lb Macaroni
4 oz butter
1/4 c flour
1 c milk
2 TBSP mustard(I used plain old yellow already mixed up)
4 slices American Cheese(Its a processed cheese food!)
About a cup of Colby and Jack cheese mixed
1/2 c Cheddar cheese

Okay, toss the macaroni in a pot of salted water(abt 1 TBSP salt in the pot) and let it cook.
Meanwhile, melt the butter, add the flour and then milk to make a basic white sauce. Add the mustard, cheeses and salt to taste. Drain pasta, mix with sauce and taste. Add more cheese if it needs it. Salt and pepper. And then its good with turkey bacon and peas. Just trust me:D
