- 2 pounds (roughly 1 kg) red onions, sliced thinly
- 2 tablespoons extra virgin olive oil, plus more for drizzling
- 4 fresh sage leaves
- salt and pepper
- 4 cups (1 liter) vegetable stock
- 4 eggs (can omit or put italian sausage instead)
- 3/4 cup grated Parmesan cheese, plus more for serving if desired
- 4 slices crusty bread, toasted
- 1.In a large, heavy-bottomed stock pot, gently saute the onion in the olive oil with a good pinch of salt and pepper and sage leaves on lowest heat. Let them sweat very gently without letting them colour to release their sweetness, about 30 minutes. If they begin to get dry or stick just add a splash of the vegetable stock
