Step 1: Heat a skillet over medium high heat. Add in 1-2 tablespoons of oil then add the onions. Cook the onions, stirring often, until starting to caramelize (about 10 minutes). Turn the heat to high and add the mushrooms. Continue to sauté until the mushrooms are 3/4's of the way done and add the peppers and garlic. Cook until the peppers are tender, stirring often so the garlic doesn't burn.
Step 2: Add the Worcestershire sauce to deglaze the pan and allow to reduce until almost dry. Remove pan from heat and whisk in the butter, whisking constantly so that the butter stays creamy and doesn't break. Check for seasoning adjust with salt and pepper if needed. Spoon over steaks.
