In a small bowl, combine all the dressing ingredients and whisk until combined. You can store the dressing in an air-tight container in the fridge for up to five days.
To make a salad, grab a large bowl. Add the chopped romaine lettuce and toss with some of the dressing (use a little at first, then add more to taste, depending on how much salad you're making). Transfer to a plate, sprinkle on croutons and parmesan, and serve with grilled chicken.
