Ah I missed it! Beef tenderloin with red wine mushroom gravy is my go to meal.
It's very similar to CC's
The only changes are;
I coat the tenderloin with rosemary and the herb & garlic butter you can buy at the store in the yellow wrapper.
I also cheat with the gravy, honestly I think it's better than scratch.
Saute about 1/2cup of mushrooms in the bottom of a saucepan
Add 1/2cup of red wine, let it reduce for a few minutes.
Add 2 cups of water
Add 2 packs of Knorr Hunter Gravy.
Guys I can't tell you how good Knorrs hunter Gravy is.
If you're into German food (my mom is Swiss and her sister is a chef) The Knorrs hunter Gravy with milk instead of water makes a phenomenal Geschnetzeltes (creamy mushroom sauce).

I also use egg noodles instead of spaetzle, a delicious dish that takes next to no effort.
