  • 1 (2 pound) piece of skirt steak (about 2-inches in thickness)
  • 1/4 cup olive oil
  • 2 tablespoons brown sugar
  • 4 garlic cloves, minced
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper

avocado pesto

  • 4 cups  fresh basil
  • 1 avocado
  • 1/2 cup asiago cheese
  • 1/4 cup toasted pine nuts
  • 3 garlic cloves
  • 1/2 to 3/4  cup olive oil
  • 1/4 teaspoon salt
  • 1/4 teaspoon pepper
  • 1/4 teaspoon crushed red pepper flakes

grilled corn relish

  • 3 ears sweet corn, cut from the cob
  • 1/2 red bell pepper, diced
  • 1 shallot, diced
  • 1/4 cup chopped fresh cilantro
  • 1 lime, juiced
  • 1/2 teaspoon salt
  • 1/2 teaspoon pepper


  • In a bowl, whisk together the olive oil, brown sugar, garlic, salt and pepper. Place the steak in a baking dish or ziplock bag and pour the mixture over top. Place it in the fridge and let it marinate for at least 30 minutes or even overnight.
  • I like to remove the steak about 30 minutes before I cook it.
  • You can grill, broil or pan sear it to your liking. I tend to broil or grill it as I find that easiest. Preheat the broiler in your oven and move the oven rack as close as possible. Place the steak on a broiler pan or baking sheet and broil on each side for about 5 minutes. This usually results in a medium doneness in my oven – but since the edges are thinner, they tend to be more well done.
  • Allow the steak to rest for 10 minutes before slicing it thinly against the grain. Serve with spoonfuls of the pesto and the corn relish on top!

avocado pesto

  • To make the pesto, combine the basil, avocado, cheese, pine nuts and garlic in a food processor. Pulse until small crumbs remain, and then with the processor running, stream in the olive oil. Start with the 1/2 cup and add the extra if needed to reach the desired consistency. Add the salt, pepper and pepper flakes and blend again. Taste and season additionally if needed.
  • As a note, to toast the pine nuts, I add mine to a skillet and heat over low heat. I shake and stir until the are golden and fragrant, about 5 minutes.

grilled corn relish

  • Stir all ingredients together in a bowl until combined. You can make this a bit ahead of time if needed! It stays great in the fridge for a day or two.
