Drain the pepitas and then add them to a blender or a food processor along with the lemon juice and 1/2 cup water. Blend until a creamy consistency has formed, scraping down the sides as needed.

Add the remaining ingredients to the blender and continue to blend until smooth. Add more water if needed to thin and salt to taste.

Transfer the container to the refrigerator and chill for at least 30 minutes. Divide into individual dishes, garnish with fresh herbs and pepitas, and serve!
