In a medium saucepan, cook wild rice according to package directions.
In a large stock pot on medium heat, warm olive oil. Add mushrooms, leeks, and kale. Cook until liquid from mushrooms evaporates (about 5 mins); stirring frequently. Add in garlic and continue cooking for 1 minute more.
Whisk in flour and stir constantly for a couple of minutes. Slowly whisk in broth and half-and-half until no flour lumps remain. Reduce heat to simmer and cook until thickened. Season with salt and pepper to taste.
Divide in four separate bowls and add a scoop of rice to each serving.
Notes
The different types of mushrooms really make this soup, but you can also use just one or any combination of the three.
