Lay chicken on a sheet of greaseproof paper and lay another over the top. Using a rolling pin beat until around a quarter of an inch thick and even.
Mix flour, cayenne, garlic powder, paprika and pepper together, season then mix together with a fork. Pour breadcrumbs in a large flat tray.
Dip the chicken first in the flour, then the eggs, then the breadcrumbs. Repeat (starting with the flour) and set aside.
Heat frying oil to 170°C/330°F. Cook chicken breasts one at a time for around 4 minutes, turning all the time to ensure an even colour.
Remove from heat and allow to cool for five minutes, then add your choice of pizza toppings and bake on a tray for 5 minutes. To give your toppings some colour grill for a further five minutes at 200°c.
