Remove the roll of croissant dough from the tin and cut it into pieces. In terms of size, it's not very precise but keep about 1 to 2 cm. Put this in a large bowl.
Add the sun-dried tomatoes, basil, grated cheese, pesto and olive oil and mix it all together nicely. You don't need to knead it, so you will still have pieces of dough.
Divide the pieces of dough with extras between a muffin tin and bake in the oven for about 15 minutes or until golden brown and cooked.
