01 -  Rinse all vegetable scraps thoroughly to eliminate any dirt or debris. 
 02 -  In a large soup pot, heat olive oil over medium heat. Add crushed garlic and any onion scraps and sauté until fragrant, about 2 minutes. 
 03 -  Add all other vegetable scraps to the pot and stir for 2 to 3 minutes. 
 04 -  Incorporate bay leaf, black peppercorns, dried herbs, sea salt, and water. Bring to a boil over high heat, then reduce heat to maintain a gentle simmer. 
 05 -  Cover the pot and simmer for 35 to 40 minutes, stirring occasionally to ensure even cooking. 
 06 -  If desired, add cooked beans, lentils, or diced potatoes in the final 10 minutes of simmering. 
 07 -  Remove soup from heat. Discard bay leaf and any large, tough scraps if preferred. For a chunky texture, serve as is; for a smoother consistency, blend partially or fully with an immersion blender. 
 08 -  Stir in lemon juice and adjust salt or seasoning if necessary. Ladle soup into bowls, garnish with chopped fresh parsley, and serve hot.
