What is the name of a French béchamel sauce with cheese added?

sorry folks, you don't add cheese to bechamel to make a mornay, you add cream. bechamel is already with cheese.

First recipe I've seen on here. I hope you've started a trend!

That’s very thoughtful of you to give us the recipe. Thank you.

This is interesting never knew that mac and cheese sauce had name and some one invented it.
