Butter Beans with Parsley, Tomatoes and Chorizo

In a small saucepan, heat the butter beans in their liquid. In a large skillet, cook the chorizo over high heat until it is lightly browned and most of the fat is rendered, about 2 minutes.

In a medium serving bowl, whisk the oil and vinegar. Stir in the tomatoes, onion and parsley. Drain the beans and chorizo and add them to the bowl. Season with salt and pepper and toss. Serve warm.
