In a large pot, heat the olive oil on medium-high heat and sauté leeks until translucent. Add the stock and peas. Bring to a boil, cover and simmer for another 20 minutes. Remove from heat and add mint. Using an immersion blender, puree soup until smooth and creamy. Season with salt and pepper to taste.
