Homemade Alfredo

This is super yummy and easy!  I just need to find a way to make it more healthy...any ideas?  


Alfredo Sauce
1/2 cup butter
1 pkg. (8 oz.) cream cheese
1 cup half and half
1/3 cup Parmesan cheese
1 tablespoon garlic powder (optional)
pepper, to taste

1. In a medium saucepan, melt butter.
2. Once butter is almost melted, add the package of cream cheese. It's easiest to cut it into 4 pieces so that it melts quicker.
3. Once butter and cream cheese are mixed well together, add the cup of half and half, Parmesan cheese, garlic powder, and then shake pepper on top. Stir all together until well mixed.
4. Once it's mixed well and sauce-like, take it off the burner and set aside so it can thicken up. Stir every few moments.
5. DONE! Pour over your favorite pasta!
