Flank Steak Tacos


3 teaspoons vegetable oil, divided
2 teaspoons dried Mexican oregano
1/2 teaspoon Kosher salt
1/2 teaspoon cayenne pepper
1/4 teaspoon black pepper
2 cloves garlic, minced
1 1/2 pounds flank steak, fat trimmed
3 cups vertically sliced onion (about 2 medium onions)

2 jalapeño peppers, seeded and halved lengthwise, thinly sliced
flour tortillas
sour cream, guacamole, tomatoes, cheese (optional condiments)

    Can you please tell me what is mexican oregano? I have never heard of it. Is that the same as cilantro?

      @Dawn, No, not the same as cilantro. It’s actually a type of oregano that you can usually find in your market’s spice aisle. Not to worry… if you can’t find it you can just use regular oregano, or even cilantro if you prefer.

    Hi Lori,
    Is there any other way aside from grilling that you recommend preparing flank steak? Unfortunately, I don’t have a grill in my apartment complex.
