Step 1

Preheat oven to 400°. In a large skillet, cook beef over medium heat until no longer pink; drain. Add beans, tomato sauce and chili powder. Simmer, uncovered, until liquid has evaporated. Remove from the heat; cool. Stir in the pimientos, chiles and cheese; set aside.

Step 2

Open 1 tube cornbread swirls. On a work surface, unroll each swirl. Arrange strips of dough side by side. Press into a 12-in. circle, pressing to seal seams. Using a pizza cutter, cut dough into 8 triangles.

Step 3

On a parchment-lined 12-in. pizza pan, arrange triangles in a ring with points toward the outside and wide ends overlapping to create a 3-in.-diameter hole in the center. Press overlapping dough to seal. Repeat with remaining tube cornbread swirls on a second pizza pan.

Step 4

Spoon filling around edge of dough. Fold pointed ends of triangles over filling, tucking points under to form a ring with a small hole in the center (filling will be visible).

Step 5

Bake until golden brown, 15-20 minutes. Serve with lettuce, tomatoes and sour cream.
