Instructions

  1. Set your oven to broil and place a rack in the upper top position.
  2. In a large mixing bowl, combine the beef strips, bell peppers, onions, mushrooms, chopped cilantro, avocado oil and lemon juice.
  3. Combine all the ingredients for the spice mix in a small bowl, mix together with a fork and add to reserved meat and veggies; toss well, until evenly combined and coated
  4. Spread into an even layer onto a 18" x 26" baking sheet and place directly under the broiler (as in almost touching) for 4 to 5 minutes, checking regularly to make sure nothing burns, although a little bit of surface charring is desirable.
  5. Remove from the oven, toss gently and garnish with lemon or lime wedges, diced tomatoes, diced avocado, chopped cilantro and sour cream, if desired.
  6. Serve with flour tortillas and additional sour cream, diced tomatoes, diced avocadoes and lemon, if desired.

Recipe Notes

*It's a lot easier to slice the beef if you place it in the freezer prior to slicing until it's nice and firm but not frozen solid; about 20 to 30 minutes should do the trick.

*If you want to warm up your flour tortillas, wrap them aluminum foil and place them in the oven, on the middle rack, while the meat and veggies are broiling.
