Add the olive oil, minced garlic, oregano, basil, thyme, rosemary, crushed red pepper, and some freshly cracked black pepper (about 10 cranks of a pepper mill) to a soup pot. Cook and stir the herbs and oil over medium heat for about one minute, or until the garlic is soft and fragrant.
Add the tomato paste and brown sugar. Continue to stir and cook the tomato paste mixture over medium heat for 2-3 minutes.
Pour the crushed tomatoes and vegetable broth into the pot and stir to combine. As the soup begins to heat through, add a can of cannellini beans (with the liquid from the can) to a blender and purée until completely smooth. Pour the pouréed beans into the soup and stir to combine again.
Place a lid on the pot and allow it to come up to a simmer. Once simmering, turn the heat down to medium low and let it simmer, stirring occasionally, for 20 minutes.
After simmering for 20 minutes, add the nutritional yeast and stir to combine. Taste the soup and add salt to taste (about 1/4 tsp). Serve hot.
