Notes
Substitutions (so it always works)
No onion/garlic: use leeks, scallions, or a pinch of garlic powder and onion powder (add early so it cooks in).No broth: water + extra salt + herbs + a splash of soy sauce or a little tomato paste.
No tomato paste: skip it—just lean on herbs and a good finish of lemon/vinegar.
Want it spicy: add chili flakes, hot sauce, or a pinch of cayenne.
Want it creamy: blend part of the soup, or add a small splash of cream at the end.
Want it more “French bistro”: add thyme, bay leaf, and finish with butter and black pepper.
Want it more “Mediterranean”: add oregano, a touch of paprika, and finish with lemon and olive oil.
