Street Taco Marinade

These are THE best street tacos you will ever eat.
Adapted from Food Network. 

• 4 garlic cloves, minced
  1 jalapeno, minced (optional)
  1 large handful fresh cilantro leaves, finely chopped
  Kosher salt
  2 limes, juiced
  1 orange, juiced (I am lazy and use frozen concentrate)
  2 tablespoons white vinegar
  1/2 cup olive oil
  
  
  Add all ingredients to a food processor or blender and blend until cilantro is fine (but not juiced because gross).
  
  
  2 lbs flat iron steak, cut into small cubes
  
  
  Pour Marinade over cubed steak and let marinate for a couple of hours. Heat oil in a cast-iron skillet and scoop mostly drained cubed steak into hot pan. cook until all liquid has gone and the orange and lime juice slightly caramelize on the beef.
  
  
  Serve on mini tortillas, heated. (Either corn or flour.)
  Top with queso fresco, onion salsa, and Mexican Cream.
  
  
  Onion salsa:
  1 medium onion
  1/4 cup cilantro
  1 tbs olive oil
  Juice of 1 lime
  salt to taste (Kosher if you have it) Finely chop onion and cilantro. Add olive oil, lime and salt. (I use my food processor and just pulse it as to not overdo it).
