Taco Pinwheels

Brown beef with onions and tomatoes in large skillet over medium heat; drain. Return meat mixture to skillet; stir in dressing and seasoning mix. Cool completely.

Unroll crescent dough onto lightly floured surface; press into 12x10-inch rectangle. Sprinkle with cheese to within 1 inch of all sides; cover with beef mixture.

Roll up dough, starting at one long side; press seams together to seal. Wrap tightly with plastic wrap. Refrigerate 15 min.

Heat oven to 375ºF. Transfer roll-up to cutting board; cut into 12 slices. Place, cut sides up, on parchment-covered baking sheet. Press tops of pinwheels to flatten slightly.

Bake 18 to 20 min. or until golden brown. Let stand 1 min. before removing pinwheels from baking sheet to serve.
