Sausage Stuffed Shells

We love these easy stuffed shells featuring sausage and spinach. Combining ground sausage (pork or chicken), spinach, ricotta cheese, and tomatoes creates such a tasty dish. Every person we have ever served these to has fallen in love.

Ingredients:

• 20 jumbo dried pasta shells
• 1 pound fresh pork sausage, casings removed (see note)
• 3 medium cloves garlic, finely chopped
• 1 (14-ounce) can diced tomatoes
• 1 (10-ounce) package frozen spinach, thawed and squeezed dry (about 1 1/4 cups)
• 4 ounces ricotta cheese (about 1/2 cup)
• 2 ounces mozzarella cheese, coarsely grated (about 1/2 cup)
• Salt and fresh ground black pepper
• Warm marinara sauce, for serving (optional)
