Mash 1 can of beans in a bowl; add remaining beans, chili powder, and next 3 ingredients, stirring until blended. Stir together salsa, queso dip, and sour cream in a medium bowl.
Spoon about 1/2 cup black bean mixture down center of each tortilla. Top each with 2 Tbsp. salsa mixture.
Roll tortillas up, and place, seam sides down, in a lightly greased 13- x 9-inch baking dish.
Pour remaining salsa mixture evenly over tortillas.
Bake, covered, at 350 for 30 to 35 minutes or until thoroughly heated.
