I know it's not authentic or anything, but this recipe makes a delicious sauce and does not call for a whole stick of butter or heavy cream. Even my kids like it.
Any Cheese Alfredo-ish Sauce
4 oz light cream cheese, cubed
1 cup milk
1/3 cup grated parmesan or romano cheese OR havarti/gruyere/other cheese, cubed
3 T butter
1/2 teaspoon garlic powder
Cook all ingredients in a saucepan on medium-low until cheeses have completely melted. Stir occasionally with a whisk.
I usually toss this sauce with 3/4 lb whole wheat rotini/penne and broccoli or zucchini. Top with more shredded cheese and freshly ground black pepper.
