This is a very simple and quick soup one of my forum friends shared. The potato base makes it thick and hearty. I really liked this one and plan to make it again soon.
2 lbs potatoes, roughly chopped
1 onion, diced
6 cups broth (made mine from veggie scraps or could use half strength bullion)
2 cups zucchini, grated
1 cup powdered milk (or one can condensed milk)
Add first 3 ingredients to pot and simmer until potatoes tender. Blend with steam safe blender (could use immersion blender or just mash with potato masher as well). Add zucchini and powdered milk and simmer 2-5 minutes until zucchini tender. Season with salt and pepper, can be served with sour cream and parmesan cheese.
