Preheat your oven to 180°C/350°F/Gas Mark 4.  Split each muffin into two to make the pizza bases.  Spread a thin layer of tomato puree over the cut sides of the muffins and place on a baking tray.

Using mini bento cutters or a sharp knife, cut some fun shapes from the red pepper and set aside (we used hearts as it was close to Valentines Day at the time). Chop the remaining red pepper as finely as you can and sprinkle it over the pizza bases.  Finely chop the cherry tomatoes and add to the pizzas too.

Sprinkle over the cheese and top each pizza with the red pepper shapes to decorate.  Bake in the oven for 5-10 minutes until the cheese is melted and bubbling.

Leave to cool for a few minutes then serve - we like to have a selection of veggie sticks and some light garlic mayo for dipping with ours.
