Preheat oven to 500° F for at least 10 mins.
Set a pizza stone in the bottom of your oven, or a cookie sheet or upside-down sheet tray on the middle rack of the oven and wait 15 mins.
Place pizza directly on stone or tray. Cook for 3-6 minutes, or until cheese is bubbling and crust is crispy.

Add ½ tsp water to pasta, cover with a paper towel and heat for 45 seconds on 60% power.
Stir and microwave for 30 more seconds at 100% power, still covered. If not hot enough, stir and microwave for another 30 seconds uncovered.
Heat a non-stick pan on medium-medium high heat.
