01 - Combine lentils, water, and bay leaf in a medium saucepan. Bring to a boil, then reduce heat and simmer uncovered for 18-20 minutes until tender but not mushy. Drain, discard bay leaf, and season with salt. Set aside to cool.
02 - Combine apple cider vinegar, water, maple syrup, and salt in a small saucepan. Bring to a simmer, then pour over sliced onions in a heatproof bowl or jar. Let sit for at least 20 minutes, stirring occasionally for deeper flavor.
03 - Place avocado, parsley, basil, chives, lemon juice, garlic, olive oil, water, salt, and pepper in a blender or food processor. Blend until smooth and creamy, adding more water as needed to reach desired consistency.
04 - Divide salad greens among 4 bowls. Top each with cooled lentils, cherry tomatoes, cucumber, shredded carrots, and avocado slices. Drizzle generously with green goddess dressing.
05 - Finish with pickled onions and a sprinkle of toasted pumpkin seeds. Serve immediately while vegetables are crisp.
