What makes toast taste so much better than regular bread?

I understand that putting something in a toaster heats it up and makes it warm and crunchy, but what about this process makes bread so different?

The maillard reaction!  It's what happens when toast gets browned and meat gets roasted.  It's a chemical reaction between proteins and sugars, usually requiring heat.  The exact flavor you get is dependent on the kinds of proteins and sugars in the food.

As to why it tastes good, nobody really knows - but it *is* known that cooking food increases the digestible calories available, so we probably evolved to enjoy the flavor of the maillard compounds, because they indicated that the cooked food was more nutritious.
