Crumble half of the cheese into your serving container.
Put the soy milk, vinegar, and the salt in the blender and let stand (without blending) 5-10 minutes to curdle. Add all other ingredients and blend until smooth and creamy, adding the oil last in a slow stream.
Pour into your serving container and mix gently with the crumbled cheese.
Wash the iceberg lettuce and dry with a kitchen towel. Remove any discolored or limp leaves from the outside. Slice in half through the core, then in half again using your chef's knife. Remove the core from each of the four pieces with an angled cut.
Serve each wedge on a plate topped with a generous pour of dressing, sprinkled with the coconut bacon.
