Prepare Ingredients: Slice summer vegetables such as zucchini, bell peppers, and carrots into thin strips. Mince garlic, ginger, and chili.
Sauté Aromatics: In a pot, heat a little sesame oil and sauté garlic, ginger, and chili for 1–2 minutes until fragrant.
Add Vegetables & Broth: Add sliced vegetables and pour in vegetable broth. Bring to a gentle simmer for 5–7 minutes until vegetables are tender but crisp.
Add Miso: Remove a small amount of hot broth, dissolve miso paste in it, and stir back into the soup. Avoid boiling to preserve miso flavor.
Season & Serve: Taste and adjust seasoning with soy sauce or a splash of lime juice. Garnish with chopped green onions, cilantro, or sesame seeds. Serve hot or warm.
