This is a great recipe I got from a Betty Crocker magazine. I tweaked it a little, trying to lower the fat & calorie content. Its VERY easy to throw together, and the slow cooker does all the hard work.
This recipe is the easiest lasagna I've ever made, especially since you do not boil the noodles. It's meatless, yet my family (carnivores included) enjoys it. This is based on a recipe I found in the Betty Crocker Low Fat Low Cholesterol cookbook.
VARIATIONS: For those who aren't watching their weight, feel free to use the full-fat versions of the cheeses. Also, you may use regular lasagne noodles instead of whole wheat.
