In a microwave safe dish, combine butter or margarine (briefly microwave butter if it is too hard to mash), minced garlic, garlic powder and Italian seasoning until well blended. Heat in the microwave for 30 seconds or until completely melted. Let sit in the microwave so it stays melted.
When spaghetti is finished, drain and place in large serving bowl. Pour butter mixture over the top and then cover in Kraft Parmesan Cheese. Salt to taste. Serve immediately. (This is also a good leftover, hot or cold.)
