A quick sauce to be used for tacos or as a dip with tortilla chips.
In a small bowl, combine parsley, olive oil, capers, lemon juice, oregano, and garlic.
Stir mixture until well blended; season with salt, if desired.
If not using immediately, this sauce should be refrigerated. Cover with plastic wrap, pressing it directly on the sauce to preserve the bright color. The sauce will keep for up to 3 days.
