Once you start making dressings from scratch, you'll never buy another bottle of preservative (and expensive!) packed dressing. It is so simple- you probably already have everything you need at home. It took me 3 years of cooking to get around to making dressing from scratch... I thought it was too much of a hassle, or difficult, or... well, involved. I was wrong - so, so easy. I highly, HIGHLY recommend it.
You can make this dressing in a bowl, and whisk it together with a fork, or make it in a jar and shake it up. The recipe is very versatile - add parmesan cheese, fresh herbs (basil or thyme would be great), minced garlic, and/or sugar/honey for a sweeter dressing.Lemon Vinaigrette
