Vinaigrette Recipes

Options
Anyone have any good vinaigrette recipes they want to share? With summer upon us, and the intense heat I want to spend as little time a possible in my kitchen, so salad have become my go to, and I like to use different vinaigrettes so I don't get bored. I just bought lemon vinegar and sherry vinegar.
Yesterday I was experimenting and I came up with a really good one, 2 parts lemon vinegar, 6 parts olive oil, a garlic clove for every part vinegar, and 1 part tequila, because I love being Mexican, and because why not? And chili powder to taste. It's great and summery!
Any one have a recipe they want to share?
