Well - meater thermometer let me down. Middle may have been MR, but the outside was Medium Well.
So, few things.
1 - suggest smaller beef fillet. I think the size is too hard to get a nice MR all around.
2 - mustard is too harsh...if I do again, dijon is not the answer. And I like mustard.
3 - mushrooms and prosciutto were non existent. Think I expected more from this.
4 - pastry part was nice.
Meal wasn't trash - but I'll probably never make this again.
Dogs liked it...they said make it again.
