Sofrito-Marinated Steak

I found this delicious recipe in the 'Dinner Tonight!' column in the Chicago Tribune. You can marinate this for as little as 30 minutes but 2–3 hours is best. I've included the 30 minute marinading time in the prep time. If you don't have a food processor just chop the vegetables as small as possible and place in a blender with the olive oil and puree.
