Chop the olives, roasted red pepper, capers, and garlic clove until they are as chunky or fine as you prefer. If you prefer your tapenade to be super fine then you can pulse these ingredients in a food processor.

Add these ingredients to a medium-sized bowl and add in the olive oil, vinegar, oregano, and red pepper flakes. Use a spoon to stir all of these ingredients until they are thoroughly incorporated.

Chill the tapenade in your fridge for 30 minutes to 1 hour before serving it with crackers or crusty bread.
