Duck with Sage Butter and Red Pepper

I'm drawn to culinary minimalism, although I still have a long way to go. But one must try - and today, I've put a duck on the fire.
I chose duck because it's so beautiful in itself, good and so... premium, that it doesn't need company to be a complete dish.
The duck is first seared on both sides before it goes into the oven. Supposedly, this keeps the juices inside the meat and the dish doesn't dry out.
The fillet is served with sage butter and red pepper. Nothing more is needed, you can put such a piece on a sandwich, eat it alone, or serve it with potatoes, rice, or whatever you want. In every option, it will be really good.
