16 oz box penne, cooked and then mixed with one jar of spaghetti/marinara sauce
(I'm in love with Kroger's parmesan & romano pasta sauce- it's so, so good)
Spread the pasta/red sauce into a 9x13 dish
Top with white sauce:
4 T butter, melted in a pan
1 c. Evaporated milk (I've used milk tons and it's fine)
4 oz cream cheese, softened
1/2 c to 1 c. Parmesan cheese (I use a Parmesan/Romano blend that I grate with my microplane)
Let white sauce simmer until it thickens a little, then pour evenly on top of noodle/red sauce mixture.
Top with 2 c mozzarella cheese, and bake at 350 for 30-40 minutes, until bubbly and a little crispy.
