Peel strips of the lemon's yellow rind with a julienne vegetable peeler or a very sharp knife (CAREFULLY!). Use the same lemon for the juice. Dice all vegetables as instructed above. Make a slurry of the cornstarch and water in a small bowl, and set aside.
Heat olive oil in a large sauce or soup pot over medium heat. Toss in onion and carrot and cook until soft and the onion is translucent, about 3-5 minutes. Mix dill, oregano, basil, and garlic, stirring for a minute until fragrant.
Turn heat to medium high. Pour in broth; add lemon strips and parmesan rind and bring liquid to a boil. Once a rolling boil is obtained, add ditalini and cook until al dente according to package directions. Stir in cornstarch slurry until incorporated.
Shut off the burner and add chickpeas, coconut milk, and lemon juice. Taste for seasoning, salt and pepper, and adjust as desired. Garnish with additional lemon, fresh parsley, or salty feta cheese.
