1. HEAT oven to 400ºF. Line 2 (15×10×1-inch) pans with foil; spray with cooking spray. Mix ingredients until blended; shape into 32 (1 1/2-inch) balls, using 1/4 cup for each.
2. PLACE 16 meatballs in each prepared pan. Bake 16 to 18 min. or until done (160ºF).
3. COMBINE half the meatballs with Tomato-Basil Cream Sauce or Creamy Brown Gravy. Cool remaining meatballs; freeze for later use. (See Tip, below.)
4. TIP Loosely pack cooled meatballs in freezer-weight resealable plastic bags. Lay bags flat in the freezer so meatballs freeze individually. Store up to 3 months. Thaw in the refrigerator several hours before using as desired.
