So a plan is coalescing. The asparagus and mashed potatoes were such a hit they may be repeated, and I am still sticking with the pork tenderloin plan. However, I think I can tie them all together with a semi-sauce with lots of sauteed mushrooms, somewhat like these but simmered down in a little bit more liquid with a pinch of flour.
The other part of the plan is the totally impractical dessert that requires more people to finish it so one doesn't scarf down the whole thing in one sitting. To wit: The Frugal Gourmet (remember him?) had an excellent Italian cookbook many years ago. This is where I learned that tiramisu should properly be referred to as TiraMiFuckingSu.
Picture from here. It's a showstopper, kids. And they can bring the wine.
