I found this recipe on the Kraft website. Sounds pretty tasty:
PHILADELPHIA CHEESY BACON TOPPER
1 pkg (8 oz) Philadelphia Cream Cheese
1/3 cup Oscar Meyer Real Bacon Bits
1/4 cup Grey Poupon Country Dijon Mustard
1/2 cup Kraft Mozarella Shredded Cheese
Place unwrapped block of cream cheese on microwaveable plate. Top with bacon bits, mustard and cream cheese. Microwave on high for 45 seconds. Serve with Ritz crackers. Makes 24 servings.
