twisted -“If you peel off the sauce and cheese from one slice and scrunch up the crust, you wont have a k’betzho or more? How about if you hold a kzayis is the size of a medium big olive?”
I honestly don’t understand your point. I tried to find R’ Moshe’s Teshuva about pizza, but I couldn’t. Let’s say that pizza is a Mezonos – if you do a web search -a lot of Kashrus agencies say that it is – and they say two is a Hamotzay. Now how could two be a Vaday Hatmozay? This I did find in the Teshuvous that R’ Moshe says 4 K’beyos is a Seudah. I really doubt two slices is four eggs for sure.
