I only tried making this once so I don't really know the exact measurements, but all you need is an avocado, a lemon, water and a food processor. You can try using half an avocado. Maybe 2 tablespoons of water. I would recommend not using the whole lemon otherwise it's probably going to be a little too sour, so maybe half a lemon depending on how sour you want it to be. Throw the half of an avocado, half of a lemon and 2 tablespoons of water into a food processor and that's it! It's a nice dressing, more on the thick side so it doesn't all drip off the lettuce onto the bottom of your bowl. I really think it's good just with the avocado, lemon and water, but you can definitely throw whatever else you want in there and I'm sure it'll turn out great!
Nice idea! I usually cut an avocado into little cubes for my little girl, with a sprinkle of lemon juice, salt and garlic powder...I bet she would love it as a dressing to mask any foods that she doesn't like!
I am actually thinking of making something similar but blending avocado and a fresh orange for a dressing. I am going to an all raw vegan potluck in May and am thinking of doing this. I am picturing romaine or collard leaf wraps with shredded raw sweet potato, jicama, onion, and avocado dressing.
