Baked Ziti

this is kind of granola but we are getting old and so we are trying to eat healthier. we try to do a vegetarian dish a week. this is our try for the week sans the meat (from the original recipe). it's still hearty and would probably be good for a freezer meal, even though i haven't tried to freeze it yet.

Ingredients

• Salt
• 1 pound ziti
• 1 medium onion, chopped
• 3 cloves garlic, chopped
• 1 (28-ounce) can diced tomatoes
• 6 ounces pesto
• 15 ounces ricotta cheese
• 1 (9-ounce) package washed spinach
• Butter, for baking dish
• 2 cups shredded mozzarella, plus more for topping
• 1 1/2 cups grated Parmesan, plus more for topping
  

Directions
Preheat oven to 375 degrees F.

Bring a large pot of salted water to a boil over high heat. Add ziti and cook until al dente. Drain in a colander.

In a large skillet over medium heat, saute onion and garlic. Add the can of diced tomatoes and pesto and let simmer for 10 minutes.

Add the ricotta cheese, spinach, Parmesan and mozzarella to a large bowl, and stir to combine.

Butter a 4-quart baking dish, add the cooked pasta, then tomato mixture and cheese mixture. Top with a sprinkling of mozzarella and Parmesan.

Bake until completely heated through and golden and crisp on top, about 20 minutes.
