Place the herbs and garlic into a blender or food processor.
Add the vinegar, red pepper flakes, and salt and pepper to taste.
Pulse a few times.
Then continue pulsing while adding 1/4 cup of the olive oil. Keep pulsing until the mixture is pretty smooth, but leave just a little texture to the herbs. Add a little more olive oil and keep pulsing until you reach desired consistency.
Serve over warm steaks, chicken, or seafood.
Notes
This makes enough sauce for 4-6 steaks.
