In a small bowl, add the minced garlic, extra-virgin olive oil, red wine vinegar, lemon juice, Dijon mustard, dried oregano, salt, and a few grinds of black pepper. Whisk together until the dressing is well emulsified.
Taste the dressing and adjust the seasoning if needed. Let it sit for a few minutes to let the flavors blend. Drizzle over your salad or store in a sealed container in the refrigerator for up to 1 week. Shake or whisk again before using.
