Chill your ingredients first if time allows — place the cucumber, green pepper, and even your blender jar in the refrigerator for 30–60 minutes before starting for the coldest, most refreshing result.

Add the chopped cucumber, green bell pepper, garlic cloves, and jalapeño (if using) to a high-powered blender. Blend on high for 30–45 seconds until the vegetables are fully broken down and smooth.

Add the ripe avocado, fresh parsley or cilantro, olive oil, lemon juice, cold water (or vegetable broth), salt, black pepper, and cumin (if using) to the blender.

Blend on high for 60–90 seconds until completely smooth and creamy. Stop and scrape down the sides as needed. The soup should be vibrantly green and velvety in texture.

Taste the soup and adjust seasoning — add more salt, lemon juice, or olive oil as needed. If the soup is too thick, blend in additional cold water one tablespoon at a time until you reach your desired consistency.

Transfer the gazpacho to a large bowl or pitcher and refrigerate for at least 30 minutes before serving. For the best flavor, chill for 2–4 hours or overnight. The flavors will deepen and meld beautifully.

Before serving, taste once more and re-season if needed — cold dulls flavors slightly, so a pinch more salt and a squeeze of lemon often helps after chilling.

Ladle into chilled bowls and garnish with thin cucumber slices, a drizzle of good extra virgin olive oil, fresh herbs, a sprinkle of flaky sea salt, and any optional toppings of your choice. Serve immediately.
