Preheat oven to 425°.
Combine first 4 ingredients in a blender; process until smooth. Combine chicken and cream cheese in a large bowl. Stir in 1/2 cup salsa mixture. Reserve remaining salsa mixture.
Bring broth to a simmer in a medium skillet. Working with one tortilla at a time, add tortilla to pan; cook 20 seconds or until moist, turning once. Remove tortilla; drain on paper towels. Spoon about 1/4 cup chicken mixture down center of tortilla; roll up. Place tortilla, seam-side down, in an 11 x 7-inch baking dish coated with cooking spray. Repeat procedure with remaining tortillas, broth, and chicken mixture.
Pour remaining salsa mixture over enchiladas; sprinkle evenly with queso fresco and chili powder. Bake at 425° for 18 minutes or until thoroughly heated. Serve with lime wedges. Garnish with cilantro sprigs, if desired.
