re: Good marinade for flank steak?

I brown garlic over low heat for about 40 minutes in 1/12 cups olive and then strain and mash the garlic into a paste. Rub the flank steak with the garlic and 1 1/2 tbsp salt and 1 1/2 tsp pepper. Reserve a tablespoon or two of the garlic paste.

Then whisk 1 1/2 cups frsh squeezed lemon juice with 3/4 cup of olive oil and 2 tablespoons of dried oregano.

Place the flank steak in a baking dish and marinate with the lemon marinade for about an hour at room temperature.

Grill to your liking and rub the remaining garlic paste on the steak and serve. Be sure to slice the flank steak against the grain and at a diagonal (45 degree) angle for maximum tenderness.

A bonus is that you get to save the garlic infused olive oil for a future project.
