I love Pizza so much, but buying it gets so expensive.  Do you know how hard it is to make pizza?
Yes I have tried making it and it can be hard to master. Pizza consists of a yeasted flatbread which is the hardest part to make and topped with tomato sauce and cheese and then baked in an oven.
I have always been afraid to use yeast, isn't it really tough to get it right?
Yes it is hard to get right as the room for error is small. Despite this, modern pizza have become popular and common in many areas of the world.
Yeah maybe it would be best for me to just buy them.  I live in the US what are the best places to buy pizza here?
I think best places to buy pizza are places like Domino's and FreshSlice. Restaurants or chains that specialize in pizza are called pizzerias.
What is FreshSlice?
FreshSlice is a brand that is popular in Canada, where I live. I thought it was in America too. Funny thing is that they do not do pizza delivery even though it is common in some parts of the world.
