Each pizza has equal no of breads and equal no of toppings. This means that pizza can be a combination of 1 bread (can be chosen among 2) and 1topping ( can be chosen among 6 ) OR can be a combination of 2 breads (can be chosen among 2) and 2 toppings( can be chosen among 6 )
=
2C1*6C1 + 2C2*6C2 = 27
