To prepare chimichurri, combine first 8 ingredients in a food processor; process until smooth.
To prepare steak, rub steak with cumin, 1/2 teaspoon salt, and pepper. Heat 1 teaspoon oil in a large nonstick skillet over medium-high heat. Add steak to pan; cook 3 minutes on each side or until desired degree of doneness. Remove from pan; let stand 5 minutes. Cut steak diagonally across grain into thin slices. Serve with chimichurri.
We cooked the steaks on the bbq, otherwise made to recipe. Chimichurri sauce was quick, easy, and added zest & brightness to the meat. Served with spinach salad, rice pilaf & steamed carrots. Pretty good.
