Serves: 6 

Prep Time: 10 minutes

Cook Time: 1 hour

Ingredients:

• 1 yellow onion
• ¼ teaspoon kosher salt
• 4 tablespoons avocado or olive oil, divided
• 1 demi baguette, cut diagonally into 1/2 inch slices
• ½ lb flank steak
• 1 tablespoon Harmony All Purpose Blend
• 3 oz softened blue cheese (or soft cheese of choice)
• ½ cup arugula
• Harmony Citrus Finishing Salt
  

Instructions:

1. Take the steak out of your refrigerator and let it rest on the counter for 30 minutes before cooking
2. Make the caramelized onions: In a large skillet over low heat, add 1 tablespoon olive oil and onions and season with salt. Cook until the onions are caramelized and deeply golden brown, stirring occasionally. This will take about 45 minutes to 1 hour.
3. When the onions are about halfway done, preheat the oven to 425ºF. Brush the baguette slices with 1 tablespoon olive oil, then arrange on a baking sheet. Bake until golden brown and crisp, about 8 minutes.
4. Season steak on both sides with Harmony All Purpose Blend, using your fingers to rub in the seasoning. Heat 1 tablespoon olive oil in a cast iron skillet over medium high heat, then cook the steak for 3-5 minutes per side, depending on your desired doneness. Let rest for 5 minutes, then slice into thin strips the same length as the crostini (2-3 inches).
5. Spread a layer of blue cheese on each crostini, then top with a spoonful of caramelized onions, a slice of steak, a piece of arugula, a drizzle of olive oil, and a sprinkle of Harmony Citrus Finishing Salt. Serve on a platter immediately.
