This spinach and ricotta lasagna recipe came after a few attempts. I wanted to make it without using white sauce. The dish is lighter this way. If you are like me, you might prefer to use fresh spinach. Just make sure you wash them well. Pine nuts add a nice touch.
Similar recipes I found out there contain either tomato sauce or white sauce. I tried a number and they are good. If you want something slightly different, my variant is tasty and enhances the flavor of spinach.
