What beracha do sefardim make on pizza? Does the amount of slices eaten make a difference?
According to Rav Bentzion Abba Shaul 2:perek 12:5 that if the dough is plain(not mixed with milk or oil) and tomato sauce and cheese is placed ontop not inside the dough it is hamotzei. See footnotes as well. It also seems that the amount of slices make no difference since it is considered pas.
