Spinach Lasagna Roll-ups

These have been all across my pinterest page and I had all of the ingredients on hand so I tried them tonight. This picture is of them un-cooked, but they turned out great.

• 12 uncooked lasagna noodles
• 2 eggs, lightly beaten
• 2-1/2 cups ricotta cheese
• 2-1/2 cups (10 ounces) shredded part-skim mozzarella cheese
• 1/2 cup grated Parmesan cheese
• 1 package (10 ounces) frozen chopped spinach, thawed and squeezed dry
• 1/4 teaspoon salt
• 1/4 teaspoon pepper
• 1/4 teaspoon ground nutmeg
• 1 jar (26 ounces) meatless spaghetti sauce
