Step 1

Make the dressing: In a food processor or blender, combine the cottage cheese, mayonnaise, lemon juice, water, onion powder, garlic and pepper and process until smooth and creamy. Add additional water, 1 teaspoon at a time, if you prefer the dressing a bit looser. Add the chives and/or parsley, and pulse to incorporate. Taste, and season to taste with salt and/or more lemon juice, if desired.

Step 2

Make the salad: Cut the romaine hearts in half lengthwise, keeping the stem intact so the leaves on each piece stay together. Place each lettuce half onto a plate, drizzle with the dressing, then arrange the tomatoes and chive and/or parsley garnish on top.
