Preheat oven to 360 and cook lasagna noodles to al dente. Drain noodles.

Meanwhile, mix together chicken and one jar Alfredo sauce.

In another bowl, mix together ricotta and drained, thawed spinach. (Make sure to drain all liquid out of spinach or your lasagna will be runny.)

In 9x13" baking dish, layer one layer of lasagna noodles.

Then pour chicken & Alfredo mixture, and sprinkle on top with one cup Mozzarella.

Place another layer of noodles on top of that, and spread spinach & ricotta mixture next.

Pour 1/2 cup of remaining Alfredo sauce on top of spinach mixture, and spread out.

Then add another cup of mozzarella over the sauce, and one more layer of noodles.

Top with remaining Alfredo sauce, 2 cups of mozzarella, and salt and pepper to taste.

Bake at 350 for 50-60 minutes ~ enjoy!
