Preheat the oven to 375°F.
Split the squash in half lengthwise, scoop out the seeds and innards. Coat baking sheet with olive oil, and place squash cut side down.
Bake until very tender when pierced with a fork, about 45 minutes. When the squash is finished baking, flip it cut side up to cool.
While squash is baking, in a large soup pot sauté onion in 2 tbsp olive oil until soft and deep golden.
Add the celery, bay leaf and black pepper and continue to sauté until the celery is tender.
Add broth and red lentils to the pot and simmer gently for about 30 minutes, until the lentils are very soft.
Scoop the squash out of its skin and add to the soup, along with the tomato paste and grated apple. Let this mixture simmer, about 30 minutes. All of the components should begin to meld.
While the soup is simmering, split the red bell pepper in half, remove the stem and seeds and place it cut side down on an oiled baking sheet. Spread the corn on the same baking sheet and drizzle 1 teaspoon of olive oil over it.
Preheat the broiler and broil the vegetables until the corn is slightly charred and the skin of the pepper is black and blistered. You may have to remove the corn first. Keep an eye on it. It should take about 5-7 minutes.
Remove the pepper to a small bowl and cover it with a plate. Let it steam there until it’s cool enough to handle, then dice it. Let the corn cool on the pan, then mix it with the red pepper dice. Season the mixture to taste with salt. Set aside.
In a pan, sauté the minced garlic in olive oil, but don’t let it brown.
When the garlic smells fragrant, add the chopped greens and sauté until they are wilted, about 10 minutes. Season with apple cider vinegar and salt to taste. Set aside.
Remove the bay leaf from the soup pot. Using an immersible blender, blend the soup until it’s smooth. Add extra broth or water, if necessary, to thin it.
Add the lemon juice, lemon rind and salt to taste.
