Combine ingredients in a bowl: 1 cup extra virgin olive oil, 1/4 cup fresh lemon juice, 1 teaspoon Dijon mustard, and 1 clove minced garlic.
Whisk together until well combined to create a smooth and glossy texture.
Add 1 teaspoon honey (if desired for sweetness), 1/2 teaspoon red pepper flakes, 1/2 teaspoon salt, and 1/4 teaspoon freshly ground black pepper; whisk again to incorporate all flavors.
Taste and adjust seasoning as necessary to suit your palate.
Transfer the vinaigrette to a jar with a lid and refrigerate until ready to use.
