Sauté the garlic, onion, and ginger in about 2/3rds of the olive oil on medium-low heat until soft and translucent, approximately 10 minutes.
Add the remaining olive oil and increase the heat to high.
Add the zucchini and stir until it is vibrant in color, approximately 3 minutes.
Add the wine and deglaze the pot while cooking off the wine, approximately 1 minute.
Add the stock and lemon thyme and bring to the boil.
Reduce the heat to low and simmer for approximately 30-40 minutes.
Remove from the heat and purée in a blender or in the pot with a stick blender.
The juice of 1 lemon can be stirred in just before serving to give it a real lemon kick (optional).
Season to taste and serve.
