How to Make It
Preheat oven to 350°.
Remove one chile from can. Chop chile. Reserve remaining adobo sauce and chiles for another use. Combine sour cream and chile in a medium bowl; let stand 10 minutes.
Place half of beans in a food processor; process until finely chopped. Add chopped beans, remaining beans, and corn to sour cream mixture.
Spoon 1/2 cup bean mixture down the center of each tortilla. Roll up tortillas; place, seam side down, in an 11 x 7-inch baking dish coated with cooking spray. Spread salsa over tortillas; sprinkle with cheese. Cover and bake at 350° for 20 minutes or until thoroughly heated.
Half of the beans are finely chopped to give the filling a thick, creamy consistency. This dish can be made up to 8 hours in advance and chilled; just bring it back to room temperature before baking.
