Grease a large baking sheet with cooking spray. Place cooked lasagna noodles in an even layer on top.
In a medium bowl, mix the ricotta, 1 egg, garlic, and salt and pepper (to taste) together.
Spread the mixture evenly onto each lasagna noodle.
Sprinkle with shredded mozzarella cheese.
Fold each lasagna noodle three or four times (See Note #2) to create a square.
Freeze on prepared baking sheet until firm, about 30 minutes.
When ready to cook, put the flour, remaining eggs, and bread crumbs into three separate shallow bowls or containers.
Whisk eggs until beaten and season the bread crumbs with salt and pepper to taste.
Working in batches, dredge the lasagna squares in the flour, followed by the eggs, and finally into the bread crumbs to coat.
In a large skillet, heat 1 1/2 inches of oil over medium heat until it reaches about 350 degrees.
Using tongs, add 3 or 4 lasagna squares and cook until golden, about 2-3 minutes per side.
Drain lasagna squares on a plate or pan lined with paper towels.
Serve with grated parmesan and warmed marinara sauce.
