Step 1

Melt butter in large saucepan over medium-high heat. Add celery and cook until beginning to soften, about 3 minutes. Stir in chili powder and garlic and cook until fragrant, about 30 seconds.

Step 2

Stir in beans, tomatoes and their juice, broth, and hot sauce and bring to boil. Reduce heat to medium-low; cover; and simmer until flavors have melded, about 15 minutes, stirring occasionally.

Step 3

Using back of wooden spoon, mash some beans against side of saucepan until chili is slightly thickened. Stir in chicken and cook until warmed through, about 2 minutes. Season with salt to taste. Serve with sour cream, blue cheese, and extra hot sauce.
