Early in my marriage I knew I'd need a lot of help in the cooking department and came across a great booklet at the grocery checkout called Lawry's Weekday Gourmet. Over the years the booklet fell apart but I made sure to save this family favorite.
When I'm choosing a recipe I have two major criteria; it has to be very flavorful, and not have a lot of fussy ingredients. This one definitely fits the bill.
*I sometimes substitute with Monterey Jack cheese if I don't have Mozzarella on hand.
Instructions: Heat oven to 350º F.
In large skillet, crumble Italian sausage. Brown 5 minutes; drain fat. In small bowl, combine milk and flour; blend well. Stir milk-flour mixture into sausage; bring to a low boil, stirring occasionally. Stir in pasta, cheeses, garlic powder, and pepper. Place in 1 1/2-quart baking dish.
Bake for 25 minutes.
Sprinkle bread crumbs on top and place under broiler just until crumbs are browned. (I sometimes skip this step).
farragio hint: 1/4 pound cooked diced ham or bacon can be substituted for sausage.
