Ingredients

Instructions

  1. Step 1: In a bowl, whisk together 3 tbsp olive oil, 2 tbsp red wine vinegar, 4 minced garlic cloves, 1 tsp dried oregano, 1 tsp salt, and 1/2 tsp black pepper to make the marinade.
  2. Step 2: Place 1 lb sirloin steak in a shallow dish and pour the marinade over it, turning to coat evenly. Let marinate for 15 minutes at room temperature.
  3. Step 3: While steak marinates, preheat oven to 425°F. Toss 3 cups mixed vegetables with 1 tbsp olive oil and a pinch of salt and pepper, then spread on a baking sheet.
  4. Step 4: Roast vegetables for 15 minutes until tender and edges are slightly caramelized.
  5. Step 5: Heat a cast iron skillet over high heat. Remove steak from marinade, shaking off excess, and sear for 4 minutes per side for medium-rare, or longer to desired doneness.
  6. Step 6: Let the steak rest 5 minutes before slicing thinly against the grain. Serve sliced steak alongside the roasted vegetables.
