Making salad dressing at home is so simple, and it's much healthier (and cheaper!) than store bought. You just need 4 simple ingredients: Olive oil, an acid (vinegar, lemon juice, etc.), salt and pepper. You can dress it up with fresh herbs, garlic, etc. but at its core - it's just those 4 ingredients! This simple dressing is packed full of flavor, using a mixture of lemon juice, herbs, olive oil and garlic. You can whisk the dressing, or even easier: put all of the ingredients in a mason jar and give it a good shake.
