Preheat the oven to 350ºF.
Bring a pot of water to a boil and add salt. Cook the lasagna noodles according to the package directions.
Once the lasagna noodles are cooked, lay them out in a single layer on a plate or sheet pan sprayed with nonstick spray or brushed with a drop of oil.
If using spinach, saute 1-2 cups in a skillet with 2 teaspoons of olive oil and a pinch of salt.
In a large bowl, whisk together the ricotta, all of the filling ingredients, 1 cup of mozzarella (save the rest), and mix until combined. Place roughly 2-3 tablespoons of the mixture on each lasagna noodle. Spread the ricotta filling out all over the noodles.
Roll up each lasagna noodle tightly from the end.
Spoon ½ cup or so of desired sauce in the bottom of a 9x13 inch baking dish. Alternatively, you could use a 12-inch oven safe skillet too.
Place the lasagna roll ups seam-side down in the dish. Pour the remaining sauce over top of the rollups and sprinkle the mozzarella cheese on top. Bake for 25 to 30 minutes, until golden!
