Why You Will Love It

Light but filling: The combination of tofu and mushrooms makes this soup satisfying without being heavy or creamy.

High in plant protein: Tofu provides a clean source of protein, making this soup suitable as a standalone meal.

Quick and simple: Minimal prep and a short cooking time make it perfect for busy days.

Clean, bright flavors: Black pepper and lemon juice add warmth and freshness without overpowering the vegetables.

Customizable texture: You can easily adjust the thickness by changing the amount of water or corn flour.

Good To Know

This soup follows a very simple principle: sauté, simmer, and gently thicken. Each ingredient is cooked separately at first to preserve its texture. Mushrooms are sautéed just until they release moisture, bell peppers are kept slightly crunchy, and tofu is lightly warmed so it stays intact.

Corn flour is used sparingly to give the soup a light body without turning it creamy or starchy. Lemon juice is added at the very end to keep its flavor fresh and sharp. The result is a clear, lightly thickened soup that feels restorative rather than indulgent.

This style of soup works especially well when you want something warm and protein-rich but easy to digest.

Serving Suggestions

• Serve as a light lunch with toasted bread or crackers
• Pair with a simple grain bowl or salad
• Enjoy as a starter before a larger meal
• Add chili flakes if you want extra heat
• Drink it as is on days when you want something very light
