Size-Wise

Substitute
Substitute 1 pkg. (10 oz.) frozen chopped spinach for the browned ground beef. Thaw spinach; squeeze out excess liquid. Prepare as directed, covering each ricotta layer with 1/3 of the spinach.
Shortcut
Adding water to the sauce helps cook the traditional noodles during baking, so you don't have to cook them beforehand. This saves you 15 to 20 minutes of prep time.
