Sirloin Steak with Balsamic Mushrooms

As a careful shopper, I got the smallest sirloin steak available at my market in order to make Sweet & Salty Beef Salad, which meant I had 8oz remaining after making the salad.  I went digging through my recipes and found this little dish, which only required the purchase of mushrooms--the rest of the ingredients were already in the house!  That's how we keep from wasting food!

• 2 tsp + 1 Tbsp balsamic vinegar, divided
• 1 medium garlic clove, minced
• 1/2 tsp dried oregano, crumbled
• 1/8 tsp pepper
• 8 oz boneless sirloin steak, trimmed of fat, halved
• 2 tsp olive oil, divided
• 6 oz button mushrooms, sliced
• 1/4 C beef broth

1.  In a medium (nonmetallic) bowl, stir together 2 tsp vinegar, garlic, oregano, and pepper.  Add steak, turning to coat.  Cover and refrigerate at least 30 minutes or up to 8 hours, turning several times if marinating longer than 30 minutes.
2.  In a large skillet, heat 1 tsp oil over medium-high heat, swirling to coat the bottom.  Cook steaks for 4-5 minutes on each side, or until browned and of desired doneness.  Transfer to plates.  Cover with foil to keep warm.
3.  In the same skillet, heat the remaining 1 tsp oil, swirling to coat the bottom.  Cook mushrooms over medium heat for 2-3 minutes, or until they start releasing their juices.  Pour in the remaining 1 Tbsp vinegar and the broth, scraping to dislodge any browned bits.  Cook for 5 minutes, or until most of the liquid has evaporated, stirring occasionally.  Serve over the steaks.

Robyn's notes: this is actually a fairly low-cal dinner!  Each serving of steak with mushrooms will be about 200 calories (try to use beef broth without extra salt and fat-free if you can find it).  This would go well with a spinach salad and maybe some garlic toast.  Watch me demonstrate this recipe on youtube!

*** 3 Stars: Good. At least one of us liked this enough for me to make it again, but not often
