Ingredients You'll Need
1/4 cup olive oil
1 medium onion (peeled and thinly sliced)
2 tablespoon chopped fresh celery leaves (and/or flat-leaf parsley or basil leaves)
4 large leaves of Swiss chard, lacinato kale, Savoy cabbage, or any other dark, leafy green, (ribs removed and discarded and leaves roughly chopped)
1/4 cup red wine
1 1/2 cups tomato puree (passata di pomodoro)
4 cups water
Fine sea salt, to taste (we use about 3 teaspoons)
Freshly ground black pepper (to taste)
3 to 4 slices of stale country bread, (toasted and each rubbed with the cut end of 1 clove of raw garlic that has been peeled and sliced in half, 1 slice of bread per serving. If you don't have stale bread, you can just toast fresh bread).
Optional: freshly grated aged Pecorino Toscano or Pecorino Romano cheese, for serving (you can omit this to make the recipe vegan)

4.Saute until the greens are wilted, about 2 minutes.
5.Add the wine and cook until the alcohol smell has dissipated, about 1 minute.

8.Bring to a simmer, then cover and simmer over low heat for 15 to 20 minutes.
9.Toast the stale (or fresh) bread slices.
10.Rub each toasted slice of bread with a clove of raw garlic, cut in half, before placing one slice in the bottom of each bowl.
11.Ladle the soup over the toasted bread, let sit for 1 to 2 minutes to allow the bread to soften, then top each serving of soup with a generous grating of Pecorino (if desired) and serve.
