How do you make Garlic Butter Spaghetti in the Microwave?

How do you make Garlic Butter Sauce in the Microwave?
Typically I use 4 tablespoons of butter and 1 tablespoon of olive oil for my Garlic Butter Sauce. But, I have found that if you are out of butter or avoid using it, you can substitute 4 tablespoons of olive oil and it still tastes pretty darn good.

As you’re heating it in the microwave, make sure you check and stir every 30 seconds because the garlic and parmesan cheese will have a tendency to get stuck together in a clump if you just cook it without stirring. When that happens, it’s hard to get it to disperse through the noodles.
