A simplified recipe, which works wonderfully on Churrasco or Flank Steak, or really any kind of steak.

10-12 cloves of garlic
2 tbsp fresh chopped, or dry flake parsley
1/2 to 3/4 cup light olive oil
1 to 2 tsp salt or to taste

Use a garlic press or a pilón to crush the garlic. Add oil, parsley and salt and mix thoroughly.
