Instructions

  1. Step 1: In a medium bowl, combine 1 lb thinly sliced flank steak with 2 tbsp red wine vinegar, 1 tsp dried oregano, 1 tsp salt, and 1/2 tsp black pepper. Toss and let marinate at room temperature for 15 minutes.
  2. Step 2: Preheat oven to 425°F and toss 4 cups cauliflower florets with 2 tbsp olive oil and 1/2 tsp paprika. Spread cauliflower on a baking sheet and roast for 20 minutes until golden and tender.
  3. Step 3: Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 3 minced garlic cloves and sauté for 30 seconds until fragrant.
  4. Step 4: Add marinated beef strips to the skillet in a single layer, cooking for 3-4 minutes without stirring until the edges are browned, then stir and cook another 2 minutes until cooked through but still tender.
  5. Step 5: Serve beef immediately alongside the roasted cauliflower.
