Put the steak in a ziplock bag and cover with the marinade overnight. Grill or broil in oven until internal temperature reaches 140-145 degrees. Let rest for 10 minutes. Slice against the grain. For fajitas: saute sliced onion and green pepper in olive oil (could use chipotle, garlic, or lime). Place the sliced steak and sautéed vegetables in a warm tortilla to serve.
