Combine the olive oil, vinegar, salt, and pepper in a bowl. Pour the marinade into a sealable plastic bag and add the steaks. marinate for 30 minutes.

Prepare the grill and cook the steaks for 1 minute on each side, or to your liking. brush the steaks with marinade as they cook. alternatively, you can broil your steaks in the oven by searing them first in a hot, oiled skillet over high heat (about 30 seconds on each side), and then completing the cooking under the broiler for about 2 minutes on each side (cook longer if you like your steak well done).

Serve the steaks on a bed of greens with a side of veggies.
