Butter Lettuce with Oranges Avocado and Shallot Vinaigrette

I like each of the ingredients in this one but didn't really think it was all that special. I enjoyed the vinaigrette best on the oranges and it's a really good vinaigrette with the fresh OJ included. My tasters both said they thought it was just ok. My Mom tasted of it though and didn't care for it at all, of course she doesn't like avocado and doesn't think oranges and onions go together. It looked really pretty on the plate.
