First let me say, there is no firm recipe for this dish. The ingredients are there but the amount(s) can be increased/decreased for a persons individual taste. What you see is what I like, but not necessarily the same thing someone else would like. Piossibly too spicy. If so, omit the crushed red pepper flakes. Too sweet??, use a chianti or dry red wine. Play with the recipe and get it to what you will enjoy. Prep the ingredients before you start the cooking process because this dish will come together quickly.

Add the olive oil to a fry pan. Heat to medium. Add the sliced shallots, breaking them apart. As the shallots begin to wilt, add the sliced mushrooms. Stir the items together for a couple of minutes. Add the crushed red pepper flakes, the garlic and the sliced cherry peppers. Stir together for about two minutes. Push the items around the edge of the fry pan, making a spot in the center of the pan for the steak. If needed, add a little more olive oil. Add the steak to the pan and cook, turning the steak once to cook both sides. Immediately prior to the steak being cooked to the level of your choosing, (rare, medium, etc), pour in the red wine and the red wine vinegar. Let the steak simmer for about 2 minutes. Remove the steak, place onto a platter, pour the remaining ingredients from the pan onto the steak, grab a chunk of sour dough or Italian bread, a glass of red wine and enjoy.
