For the noodles, boil 3-4 l salted water (1 teaspoon salt per litre). Cook the noodles according to the instructions on the packet. Clean, wash and cut spring onions into rings. Clean, wash and drain the rocket.
Wash the tomatoes and cut into 8 thick slices. Drain the pasta, rinse with cold water and drain well. Mix noodles and 1 egg, season with salt and pepper.
Heat 2 tablespoons of oil in a large frying pan. Oil the dessert rings and place them in the pan. Add 1⁄8 of the noodle mixture to each ring and fry over medium heat for 4-5 minutes (or roll the noodles into nests using a fork, place them in the pan, press them slightly flat and use a spatula to push them into shape).
Remove the rings, turn the pancake, fry for another 4-5 minutes, remove and keep warm. Fry 4 more noodles from the remaining noodle mixture in the same way.
Knead minced meat, 1 egg and breadcrumbs. Season with salt and pepper and form 4 flat meatballs of the same size. Heat 2 tablespoons of oil. Fry the meatballs for 8-10 minutes while turning.
Cover 4 pasta cakes with 1 burger each. Spread ketchup, tomato slices, spring onions and rocket on top. Cover with the remaining noodle. Serve immediately.
