Place your small sauté pan over medium heat and add the 1 tbsp of olive oil. Once hot, add the shallot and sauté until it begins to brown, about 5 minutes. Next, add your jalapeno, and cook for about 3 minutes. Finally, add in your garlic and cook for about 1 minute, or until the garlic is fragrant. Remove from the heat and add to your high-speed blender.
Next, get your cucumbers ready. You can peel and remove some but not all of the skin. Next, cut the cucumbers down the middle and remove all of the seeds. Now add your cucumbers, silken tofu, yogurt, basil, lemon juice, dill, salt, agave, your shallot mix, and several grinds of pepper and blend until smooth. When the blender is going, slowly pour in the olive oil, so it emulsifies and helps to thicken the soup. Chill for at least 4 hours.
Ladle into bowls and drizzle with olive oil. Garnish with the extra cucumber slices, freshly ground black pepper, and fresh dill, mint, and/or chives. Serve cold.
