First, make a sofrito by sautéing the red and green bell peppers, onion, and garlic. Once softened, add the grated tomato and chopped squid. Cook everything together for about 10 minutes.

Meanwhile, heat a little oil in a paella pan. When hot, fry the noodles until golden, being careful not to burn them. Add the sofrito and squid mixture, then gradually pour in the fish stock.

Let everything cook slowly. You'll see the noodles start to stand up as they finish cooking.

Turn off the heat and let it rest for a few minutes before serving and enjoying.
