Carne Asada Tacos

My mom, dad, Aunt Karen & Uncle Mike just announced that they are all going to Cozumel in February, being the beach lover that I am, I am insanely jealous. So to make my self feel a little better & to honor Matt's request of tacos for dinner, I am going to whip up these authentic Carne Asada tacos. Just add Margaritas to feel like you are South of the Border!

3 pounds Flank Steak
Marinade
1/3 cup White Vinegar
1/2 cup Soy Sauce
4 cloves Garlic, minced
2 Limes, juiced
1/2 cup Olive Oil
1 teaspoon Salt
1 teaspoon Ground Black Pepper
1 teaspoon Ground White Pepper
1 teaspoon Garlic Powder
1 teaspoon Chili Powder
1 teaspoon Dried Oregano
1 teaspoon Ground Cumin
1 teaspoon Paprika
Relish
1 White Onion, chopped
1/2 cup chopped Fresh Cilantro
1 Lime, juiced
Salsa
2 large Tomatoes, chopped
2 Jalapeno Peppers, chopped
1 White Onion, quartered
4 cloves Garlic, peeled
4 Dried New Mexico Chile Pods
1 pinch Salt and Pepper, to taste

1 package Tortillas (corn or flour)
2 cups grated Cheese
2 Limes, cut into wedges

Lay the flank steak in a large glass baking dish. In a medium bowl, whisk together the vinegar, soy sauce, 4 cloves of garlic, juice of two limes, and olive oil. Season with salt, black pepper, white pepper, garlic powder, chili powder, oregano, cumin and paprika. Whisk until well blended, then pour over the steak in the dish. Turn over once to coat both sides. Cover with plastic wrap, and marinate for 1 to 8 hours.
In a small bowl, stir together 1 chopped white onion, cilantro, and the juice of 1 lime. Set aside to use as a relish for the tacos.
Heat a skillet over medium-high heat. Toast chile pods in the skillet for a few minutes, then remove to a bowl of water to soak for about 30 minutes. Preheat the oven to 450 degrees F (230 degrees C).
Place the tomatoes, 1 onion, jalapenos, and 4 cloves of garlic onto a baking sheet. Roast in the oven for about 20 minutes, until toasted but not burnt. Place the roasted vegetables, and soaked chile pods into a blender or food processor, along with salt and pepper. Puree until smooth.
Heat vegetable oil in a large skillet over medium-high heat. Cut the marinated flank steak into cubes or strips. Cook, stirring constantly, until the meat is cooked through and most of the liquid has evaporated.
Warm the tortillas in a skillet for about a minute on each side to make them pliable. Tortillas may also be warmed in a microwave oven. Arrange two or three tortillas on a plate, and lay a generous amount of beef over them. Top with a sprinkle of the onion relish and a large spoonful of the pureed salsa. Add as much cheese as you like. Garnish with lime wedges, and serve.
