Servings: two.

If you can’t get medallions, buy filet mignon (tenderloin steaks) and cut them in half to a 1/2-inch thickness yourself.

Ingredients

3 oil-packed sun-dried tomato halves, drained and minced
1/4 cup unsalted butter, well softened
1/4 tsp. sherry vinegar
Kosher salt and freshly ground black pepper
4 beef tenderloin medallions, 1/2 inch thick (3/4 lb. total)
1 Tbs. olive oil
2 shallots, minced
1/4 lb. cremini mushrooms, stems trimmed and discarded; caps wiped clean and sliced about 1/4 inch thick
2 small bunches (1/2 lb. ) arugula, trimmed, washed, and dried (or 10 oz. packaged baby arugula)

Preparation

Mix the minced sun-dried tomatoes with 2 Tbs. of the butter and the vinegar. Season with a pinch or two of salt, wrap in plastic, and mold into a 2-inch-long cylinder. Put in the freezer to firm.
Season the beef well on both sides with salt and pepper. In a large skillet over medium-high heat, heat the olive oil until quite hot. Sear the beef medallions until well browned on both sides and cooked to rare, about 2 minutes per side (or longer if you like your steak cooked more). Transfer to a plate and tent with foil to keep warm. Add the remaining 2 Tbs. of butter to the pan. When it’s foaming, add the shallots, cook for 30 seconds, and add the mushrooms and a good pinch of salt. Sauté until the mushrooms are well browned, 2 to 3 minutes. Add the arugula to the pan and toss with the mushrooms, cooking just until the leaves have wilted. Arrange the sauteed vegetables on dinner plates, top with the beef, and serve with a slice or two of the chilled butter on the beef.

Really quick and easy and very tasty! Just the thing for an after work supper or a fabulous dinner party main.

I found a tenderloin on sale and sliced it into filets for the freezer. This was a great way to prepare a special, fast meal. The first time I made it I didn't have any sun-dried tomatoes, so I used roasted red peppers. (Kept the extra butter in the freezer and used it with a fish dish.) Be sure to cook the mushrooms until they are browned. It takes more than 2 or 3 minutes.

This is an awesome recipe! I made it for my family and now it is a permanent addition to my cookbook. We really didn't care for the sun-dried tomato butter, so I will not make that in the future. I also used shiitake mushrooms instead for more flavor and they were wonderful.
