One pan, and the pasta is cooked in the soup rather than drained, which is what thickens it. Draining the pasta separately gives you a thin tomato broth with pasta in it.
- Oil, dried onion and garlic two minutes. Herbs in.
- Drained carrots, chopped small, two minutes.
- Passata, stock cube, 500 ml water. Brought up to a simmer.
- Pasta straight in. Cook for the time on the packet, stirring more often than you would in water, because it will catch.
- Drained beans in for the last five minutes. Crush a handful against the pan.
- Rest it two minutes off the heat before eating. It thickens noticeably.
Serves 4. More water makes it a soup, less makes it almost a stew, and both are correct.
