As someone said, mash them with potatoes. 1/3 turnip & 2/3 potato.
We were given green beans and I steamed them but they were too tough and stringy. I put them through the blender with hot chicken broth. I ran the blender extra long to ensure the stringy stuff was gone. Then I froze the mixture to be used for soup base. I’ll add ham and diced carrots and onions. Similar to split pea soup.
