Place the oil and garlic in a large pot over medium heat. Let the garlic cook, stirring often, until the garlic becomes lightly golden.
Add the potatoes and let them cook for about five minutes, stirring ever so often, until they begin to lightly color.
Add the leeks, red pepper flakes, season with salt and ground black pepper, add the sage, and the add 10 cups of water or vegetable stock to the pot.
Add the asparagus and the wild rice. Bring the soup to a boil, then lower heat until the pot is gently boiling and let the soup cook, uncovered, for about an hour. If the soup gets too dry (it shouldn't with this much water) add some more water.
Add the chickpeas and more salt and black pepper, if desired. Ladle into bowls and drizzle on some EVOO-- it's really worth the few additional calories, trust me, and olive oil is actually good for you.
Serve hot with a crusty Italian bread or by itself. This soup is a one-pot meal.
