Clean, wash and roughly chop the spinach. Peel and finely chop the onions. Peel garlic and press it through a garlic press. Soak the rolls in cold water. Squeeze the rolls well.
Knead minced meat, half of the onion cubes, bread roll and egg. Season with salt and pepper. Cut feta into 8 cubes. Form 8 longish meatballs from the minced dough, pressing 1 feta cube in the middle of each.
Heat 2 tablespoons of oil in a frying pan and fry the meatballs for about 10 minutes. Prepare the pasta in salted water according to the instructions on the packet. Heat 1 tablespoon of oil in a frying pan. Fry the rest of the onion cubes and garlic in it.
Add the spinach and let it collapse. Pour on chunky tomatoes and season with salt, pepper and sugar. Simmer for 5 minutes. Clean and wash the cherry tomatoes and possibly cut them in half. Add to the sauce and cook briefly.
Drain the pasta and let it drain well. Arrange noodles, meatballs and spinach-tomato vegetables on plates. Garnish with oregano.
