First up, we need to preheat the oven to 200℃ (or 180℃ if you're using a fan oven).

Grab a large pan, fill it up with some water, add a pinch of salt and heat it up until it's boiling. Add the pasta and cook it for a little bit less than what it says on the packet - probably about 6 or 8 minutes.

Drain the pasta and then mix in the sauce, half of the pepperoni slices, half of the grated cheese and the tomatoes.

Next, grab a baking dish and pour in the pasta mixture. Put the remaining pepperoni on top and sprinkle with the rest of the cheese. Then it's into the oven for about 15 minutes.

And that's it - enjoy some deliciously cheesy, melty, pizza-y pasta bake.
