Ingredients

• 13 oz can basil-flavored tomato sauce
• 1 1/2 oz sliced olives, drained
• 1 cup ricotta cheese
• 1/2 cup water
• 1 tbsp freshly squeezed lemon juice
• 1 tsp dried oregano
• 4-6 uncooked lasagna noodles
• 2 1/2 cups mozzarella cheese, shredded (divided)
• 4 oz feta cheese, crumbled
• 5 oz frozen spinach, thawed and drained

Instructions

1. Prepare the Sauce:
   In a mixing bowl, combine the tomato sauce, sliced olives, and water. Stir until well blended.
2. Prepare the Ricotta Mixture:
   In a separate bowl, mix the ricotta cheese, lemon juice, and dried oregano until smooth and well combined.
3. Layer the Lasagna:
   • Spread 1/2 cup of the sauce mixture evenly across the bottom of a lasagna dish.
   • Place half of the uncooked lasagna noodles over the sauce.
   • Top with half of the ricotta mixture, 1/2 cup of mozzarella, half of the crumbled feta, and half of the spinach.
   • Repeat the layering with the remaining ingredients, finishing with a layer of noodles and the remaining sauce.
4. Refrigerate Overnight:
   Cover the dish with plastic wrap and refrigerate overnight to allow the flavors to meld and the noodles to soften.
5. Bake the Lasagna:
   • Preheat the oven to 375°F (190°C).
   • Remove the plastic wrap and bake the lasagna for 35 minutes.
6. Add the Final Cheese Layer:
   Remove the lasagna from the oven and sprinkle the remaining 2 cups of shredded mozzarella on top. Return to the oven and bake for an additional 20 minutes, or until the cheese is melted and golden brown.
7. Rest and Serve:
   Allow the lasagna to rest for 15 minutes before slicing and serving. Enjoy!
