Layer 1: Blend all ingredients in a food processor or blender until it reaches your desired consistency. Pour the mixture into the bottom of a large bowl (one big enough to hold about 10 cups), and tilt the bowl so that the mixture coats the bottom. Rinse the blender.
Layer 2: Pour the corn evenly over the black bean mixture.
Layer 3: Add all ingredients to the blender/food processor, and blend until smooth. Pour over the corn, and use a spatula or back of a spoon to spread evenly. Rinse the blender again.
Layer 4: Scatter the peppers over the creamy chipotle layer.
Layer 5: Pour the salsa over the peppers, then scatter the diced tomatoes on top.
Layer 6: Add all ingredients except the coconut milk to the blender/food processor and process until smooth. Add the coconut milk gradually as needed to blend. Pour this layer over the tomatoes, and use a spatula or back of a spoon to spread evenly. Rinse the blender.
Layer 7: Sprinkle the scallions and jalapeno slices over the avocado layer.
TIP: To prepare the limes, use a paring knife to slice off the peel and pith (the bitter white part).
