Instructions

  1. Step 1: In a shallow dish, whisk together 4 tbsp extra virgin olive oil, 2 tbsp balsamic vinegar, 3 minced garlic cloves, 1 tbsp dried oregano, 1 tbsp chopped fresh rosemary, 1 tsp kosher salt, and 1/2 tsp black pepper. Add 1.25 pounds flank steak and coat well. Marinate in the refrigerator for at least 1 hour.
  2. Step 2: Preheat oven to 425°F. Toss 1 medium sliced zucchini, 1 medium cut red bell pepper, 1 medium quartered red onion, and 1 cup grape tomatoes with 1 tbsp olive oil and a pinch of salt and pepper. Spread on a baking sheet in a single layer.
  3. Step 3: Roast vegetables in the oven for 20 minutes until tender and caramelized, stirring halfway through.
  4. Step 4: While vegetables roast, preheat grill or grill pan to medium-high heat (around 400°F). Remove steak from marinade and grill for 5-6 minutes per side for medium rare, until internal temperature reaches 135°F.
  5. Step 5: Let steak rest for 5 minutes before slicing thinly against the grain. Serve alongside the roasted vegetables.
