You might like the salad and the dressing in this one for Pineapple Ginger dressing. The pineapple completely balances with the white Balsamic vinegar, but if you prefer, you could use lemon juice or sour orange juice instead.
Or this Tangy Lime Ginger dressing.
Or this Aloha Pineapple Ginger dressing.
Or this Pesto Vinaigrette Dressing
Or this Tomato, Avocado and Pumpkin Seed Dressing
Or this Tangy Tomato Salad Dressing (you can use lemon juice instead of vinegar)
Or this Tahini Dressing (has a slightly bitter, nutty flavor)
Or this El Torito’s Caesar Dressing with Pepitos (I know you said you didn’t like creamy dressings, but this one, because of the unusual ingredient combinations, has a very unique flavor. It’s one of my favorites)
And here’s one for a beet salad with a Creamy Orange Walnut Dressing (but it uses yogurt so it has a different flavor and texture than your typical creamy mayo or buttermilk style dressing, plus the orange juice and walnut oil give it a very unique taste too).
Or this Russian Dressing (which has a nice tomatoey flavor. You can use more lemon juice and leave out the vinegar)
Or this Japanese Carrot Ginger Dressing (this recipe uses rice vinegar which is more subltle and a bit sweeter than regular vinegar, plus the addition of the ginger, carrots and miso, make this not taste like a traditional vinegar based dressing at all, but you could also replace it with lemon juice or sour orange juice if you like)
Or this Ginger Sesame Miso Dressing
Or this Tamarind Dressing on spinach salad.
Or this Lemon Soy Sauce with Herbs Dressing
Or this Basil, Mint and Orange Vinaigrette (just use lemon juice instead of the vinegar)
Or this Orange Tahini Dressing
Or this Sweet and Spicy Peanut Dressing
Or this Coconut Milk and Lime Salad Dressing (again, this is a creamy-style dressing, but the coconut milk gives it a lovely sweet taste that is completely different from mayo or buttermilk. This one has a tropical flair to it)
Hopefully there will be something on this list that you will like. : )
