In one sentence, describe what the following article is about:

If you have a lot of pizza left over, cut it apart into individual slices with a pizza cutter. Skip this step if you have only 1 slice to freeze. Most pizzas already come pre-sliced, but they are still connected along the crust. You need to separate the slices from each other completely. Tear off a piece of plastic wrap and set it on the counter. Place a pizza slice on top of the plastic wrap, making sure it's centered. Fold the edges of the plastic wrap over the pizza to cover it completely. Do this with all of the slices. Plastic wrap tends to stick to everything, so you need to create a barrier around it. Tear off a piece of aluminum foil or wax paper, then wrap it around the pizza slice. If you don't have aluminum foil or wax paper, you could try freezer paper or parchment paper. You can put more than 1 pizza slice into a freezer bag, as long as the bag is big enough. If you don't have any freezer bags, you can use another freezer-safe plastic container. Write the date on the bag or container with a permanent marker. If you don't want to ruin the container, write the date on a piece of masking tape, then put the tape on the container. Clear some space in the freezer, then place the pizza inside. Leave the pizza in the freezer until you are ready to eat it. It will stay fresh for up to 2 months. When you are ready to eat your pizza, take it out of the freezer and unwrap it. Let it thaw on a plate in the fridge for about 2 to 3 hours. Bake it in a preheated oven at 350F (177C) for 5 minutes. You can thaw and cook the pizza in the microwave, but you may not get that freshly-baked taste. For a well-done pizza, try 375F (191C) for 12 to 15 minutes instead.

Summary:
Cut the pizza apart into individual slices, if needed. Wrap each slice individually with plastic wrap. Wrap each slide with aluminum foil or wax paper to prevent sticking. Place the pizza slice(s) into a plastic freezer bag and label it. Freeze the pizza for up to 2 months. Thaw the pizza in the fridge for 2 to 3 hours, then bake it.
