Heat your oven up to 200°C. Place a pan of water on the heat to boil and cook the pasta. Since it's going to be cooking in the oven as well, drop a couple of minutes off the cooking time written on the back of the packet.

Get an ovenproof dish and pour in the pasta. Scoop the pesto on top and give it a good mix. Chop the cherry tomatoes in half and scatter over the top along with the mozzarella cheese. You could also add some extra grated parmasan or cheddar. If you have any basil, tear up the leaves and spread them out on the top,

Put the bake in the oven for about 20 minutes (or until the cheese is completely melted and started to brown). Serve while it's nice and hot.
