To make the Italian salsa verde, add the olive oil, lemon juice, hot water, garlic, oregano, parsley, mint, and red pepper flakes to a cup that you can use your immersion blender in or add the ingredients to a blender. Thoroughly blend, then place the sauce into the refrigerator for at least 30 minutes. The sauce should be quite thin but will thicken a bit in the fridge.
¼ cup extra virgin olive oil, 2 Tablespoons plus 1 teaspoon lemon juice, 2 Tablespoons hot water, 1 clove garlic, 2 teaspoons dried oregano, 2 Tablespoons fresh parsley, 1 Tablespoon fresh mint, Pinch crushed red pepper flakes
