Boil and drain the lasagna according to package directions for al dente. Add a dash of olive oil to the pasta water to prevent sticking.
Preheat oven to 375F degrees.
In a large bowl, combine the ricotta, egg, Parmesan cheese, Italian seasoning and 1 cup of mozzarella.
Lay the lasagna sheets flat onto a piece of parchment paper. Spread the ricotta filling onto the lasagna sheets. Drizzle with pesto sauce.
Roll up the lasagna sheets.
Spread half of the red sauce onto the bottom of a 9x13 baking dish. Arrange the lasagna roll ups in a single layer on top of the sauce. Top lasagna with the rest of the sauce. Top with remaining 2 cups of mozzarella.
Bake for 30-35 minutes, until cheese is melted and bubbling.
