Heat sauté pan over medium high heat. Add chorizo and cook, breaking chorizo into small pieces. Once fully cooked, remove chorizo from pan, leaving the rendered fat.
Add butter to the pan to melt. Add onions and cook until lightly browned. Add garlic and beans. Begin to mash slightly until the mixture is thick but still has a good amount of whole beans.
Add chicken stock and OLD BAY® Hot Sauce. Bring to a simmer, stirring, and continue to cook until mixture is thick and chunky. Stir in cooked chorizo. Cool completely, cover and refrigerate until service.
