Soups made from roasted vegetables are delicious. Wish I could make them more often. What do you think of miso soup? Japanese eat them for every meal and they're filling and customizable. They take 10 minutes to make because you're just stirring dashi powder and miso paste into hot water, but they have a lot of flavor. Add rehydrated wakame or some baby spinach for fiber and firm tofu cubes or an egg for protein.
