I suggest that the forbidden breakfast is tantamount to an eggs benedict, but with the hollandaise sauce replaced by a roux.

If it's forbidden, it is rather "eggs interdict".

The eggs had better be deviled, too.

Vile eggs need de-viling, otherwise not.

Oh, I do frequently have biscuits and gravy topped with fried eggs, though the biscuits and gravy would definitely pull it further towards the flour end of the spectrum, maybe not quite in the dark region.

Also, hollandaise is pretty integral to eggs benedict, I've had lots of variations but the traditional with poached egg, canadian bacon, english muffin, and hollandaise is really by far the best.

How about a Sauce Mornay?

béchamel (roux + milk) + egg yolks + cheese

So eggs with white gravy? I think I’ve had that combo and it was pretty banging.

Even easier - egg sandwich using a basic milk bread.

Add crawfish and you're really talkin
