Step 1 (Cut the Lettuce Wedges): Remove the outer wilted leaves from the chilled head of iceberg lettuce. Cut the head in half through the core, then cut each half again to make 4 equal wedges (trimming the tough tip of the core).
Step 2 (Make the Creamy Dressing): In a bowl, whisk together the vegan mayo (or yogurt), Dijon mustard, lemon or lime juice, apple cider vinegar, and minced garlic. Season with salt and black pepper. If the dressing is too thick, thin it out with a little cold water until pourable.
Step 3 (Assemble the Wedges): Place the iceberg wedges on serving plates. Top generously with the chopped cherry tomatoes, pomegranate seeds, cucumber slices, and red onion.
Step 4 (Add Crunch & Herbs): Sprinkle the roasted sunflower seeds or chopped walnuts on top for crunch. Garnish with freshly chopped chives or parsley.
Step 5 (Drizzle & Serve): Generously drizzle the creamy dressing over each wedge and serve immediately as a refreshing appetizer or light meal!
