Grilled Flank Steak, Onion, and Peppers

Ingredients

• 1 flank steak (1 1/2 lbs.)
• 1 1/2 teaspoons kosher salt, divided
• 1/2 teaspoon pepper
• 1/2 teaspoon ground cumin
• 1/2 teaspoon garlic powder
• 1/2 teaspoon paprika
• 1/2 teaspoon chili powder
• 4 tablespoons melted unsalted butter
• Juice of 1 lemon
• 1 medium onion, sliced into thirds
• 1 red bell pepper, seeded and quartered
• 1 yellow bell pepper, seeded and quartered
• 1 tablespoon olive oil
• 2 garlic cloves, minced

Preparation

1. 1. Heat a grill to high (450° to 550°). Using a sharp knife, score steak on a diagonal across the grain, making parallel lines about 1 in. apart. Turn steak and repeat to create a diamond pattern. Flip steak over and repeat scoring on the other side.
2. 2. Combine 1 tsp. salt and the spices, then sprinkle all over steak. Drizzle meat with butter and lemon juice and rub flavorings into slits.
3. 3. Grill steak, turning once, 8 minutes total for medium. Let rest. Mix onion and peppers with oil, garlic, and remaining 1/2 tsp. salt. Grill, turning often, until softened, 5 minutes. Cut vegetables into strips; serve with steak.
