Preheat oven at 180ºC. Grease a baking tray with some oil.
Sift together refined flour, milled flour and ½ tsp salt into a bowl.
Take yeast in another bowl. Add some warm water and sugar, mix well and set aside till it activates.
Make a well in the flour mixture and pour the activated yeast in it. Mix and knead into a soft dough using water as required. Place in a bowl, cover with a damp muslin cloth and set aside in a warm place to prove.
Cut the capsicums into juliennes.
Dust the worktop with some refined flour, place the proved dough on it and knock it back. Roll out into a medium thick square, dusting with flour.
Place the square on the greased baking tray. Spread pizza sauce on it and top with 3 tbsps mixed cheese, zucchini slices (reserve some), capsicum juliennes (reserve some) and corn kernels. Sprinkle some salt and top with remaining mixed cheese. Prepare a funny face using the reserved zucchini slices, capsicum juliennes and olive slices (eyes).
Put the tray in the preheated oven and bake for 15 minutes.
