It's not all that often that we do steak and potatoes, but that's what needed to be eaten, so we forced ourselves to eat it. ;-)
For the potatoes: peel and slice (1/2cm) some potatoes. Cook with a bit of salt in clarified butter over medium-high heat until nicely browned.
For the tomato sauce: cook finely chopped shallot in neutral oil until it softens. Add crushed tomatoes, minced chipotles, oregano, salt, and black pepper. Let simmer for 10-15 minutes.
For the steak: season it well and then sear in butter.
Serve the steak on top of the sauce with the potatoes beside. Top everything with chives and serve with a lemon slice.
We ate this together with a big salad.
