Course Main Dish


Ruby Grapefruit Marinade:

  • 1/4 cup ruby grapefruit juice
  • 1/4 cup lemon juice
  • 3 cloves garlic minced
  • 1/2 teaspoon chili powder
  • 1/2 teaspoon paprika
  • 1/2 teaspoon dried oregano
  • Salt to taste
  • 1/4 cup olive oil
  • 1 lb beef flank or skirt steak


  • 1 large sweet onion
  • 2 large bell peppers
  • 1 tablespoon olive oil

To assemble:

  • 8 small tortillas
  • 1 handful cilantro leaves
  • 1 jalapeno thinly sliced
  • 1/2 cup yogurt


  • Add the grapefruit and lemon juice, and seasonings, to a large zipperlock freezer bag, or a large container with a lid. Seal, and shake until the ingredients are blended.
  • Add the beef, and refrigerate from 4 to 12 hours.
  • When the beef is ready, preheat your grill (indoor or outdoor) to a high setting.
  • Slice the onion into thin wedges.
  • Remove the stems and seeds from the pepper, and cut into thin strips. Add to the onion slices in a bowl along with the tablespoon of olive oil. Toss to coat the vegetables.
  • Spread the veggies in a single layer on a grill pan, or a large piece of foil placed on the grill. Grill for about 10 minutes, until the onions are browned and the peppers are softened.
  • Keep the veggies warm as you sear the steak for about 5 minutes on each side.
  • Let the meat rest a few minutes before cutting into strips crosswise.
  • Serve with vegetables and toppings in the tortillas.
