I used to think I hated beans; yet, as a vegetarian, I needed to find a way to incorporate them in my diet to be certain of getting enough protein. I discovered that pureeing a can of beans with its liquid in a food processor and adding some olive oil, lemon juice, garlic and other seasonings of choice makes a great salad dressing. It's similar to hummus, only more liquid. So it wasn't the beans I didn't like but the texture. I use different kinds of beans for variety.
You can also add beans to soup. Pureeing them makes the soup more creamy.
