Marinate the steak: Place steak in a large zip baggie. Add marinade ingredients, zip closed and rub into the steak. Refrigerate for at least 1 hour and up to 4 hours. Remove the steak from the refrigerator and let sit at room temperature 30 minutes prior to grilling.
Prepare the salsa: Heat 1 tablespoon olive oil in a large skillet. Add the tomato and peppers and saute over medium heat until they are slightly softened. Remove from heat and stir in the lemon juice, vinegar, salt and pepper. Let sit at room temperature until ready to serve. (Alternately the salsa can be mixed together raw and served raw instead of sautéed. It's totally up to you).
Grill the steak: Preheat grill to medium. Drain the marinade and grill steak 5 to 7 minutes per side (depending on thickness and desired doneness). Let rest for 5 minutes before slicing thinly against the grain. Serve steak slices topped with a generous scoop of salsa.
Notes
Add some fresh corn or diced zucchini to the salsa if you'd like.
