Put the olive oil and butter into a large pot over medium-high heat. Add the vegetables and toss to coat them well with the fat; season with salt and pepper. Add 1 cup water and bring to a boil. Lower the heat to a simmer, cover the pot, and cook until the vegetables are tender, about 20 minutes.
Meanwhile, make the Herb Butter by combining the soft butter and herbs together; season with some salt and pepper.
To serve, spread some Herb Butter in the bottom of a bowl. Add the hot vegetables and dot with more Herb Butter. Moisten with some of the cooking liquid and serve.
