Cook the lasagna noodles following the package directions. Drain and lay them flat on a baking sheet lined with paper towels.
Prepare the ricotta by mixing it with the thawed frozen spinach, red chili flakes, salt, pepper, and lemon juice.
Using one to two tablespoons of the ricotta mixture, spread it into an even layer along each noodle.
Roll the noodle about 4-5 times until you have a rectangle. Place each noodle roll on a baking sheet with parchment paper and freeze for 45 to 60 minutes.
When ready to start frying, prepare your dredging station. In one bowl, put the milk, in another bowl the all-purpose flour, and in another one the bread crumbs. Mix the oregano, red chili flakes, salt, and garlic powder.
In a large skillet or cast iron dutch oven, heat the oil to 350ºF. While the oil reaches its temperature, working in batches, dip one roll into the milk, then into the flour, into the milk again, and then into the bread crumbs.
Fry in batches until they are golden in color in crispy on both sides, about 3 to 4 minutes per side. Drain on a baking sheet covered with paper towels when crisp and delicious.
Heat the marinara sauce and serve it in a small bowl, and set it on the side.
