For the flank steak:
Rub extra virgin olive oil on steak to lightly coat, then season heavily with Blackening Spice rub, and let sit for 30 minutes to "marinate" while making chimichurri.
For the chimichurri:
Chop up the solid ingredients (vegetables) and place in a bowl.
Add liquids next and lightly stir. Zest and juice both the lemons and limes, then stir the chimichurri again.
Add in the spices and dry herbs and mix thoroughly. Refrigerate until ready to serve with steak.
To cook:
When chimichurri is finished and cooled, cook the steak to medium-rare, and let rest 5–10 minutes before slicing and serving.
To serve: Garnish with chimichurri and torn leaves of parsley. Add salt & pepper to taste.
