Escarole is a cooking green in the chicory family. I made a delicious escarole soup, adapting a recipe from foodnetwork.com:
White Bean and Escarole Soup
Ingredients
2 Tb olive oil
2 oz pancetta or prosciutto cut into 1/4 inch cubes (I used local sausage but it could also be omitted for folks who don't eat meat)
1/2 cup onions (I used scallions, mini-onions would also work)
4 cloves garlic (I used garlic scapes)
1 tsp rosemary or thyme
1/4 tsp red pepper flakes
1 head escarole (about 1 lb) trimmed, washed, and coarsely chopped
Two 15 oz cans cannellini beans, rinsed and drained
1 cup chopped tomato (I used red peppers from the freezer)
5 cups chicken broth (can also use vegetable stock)
1 tsp salt
Freshly ground pepper
Directions
In a soup pot, heat the oil over medium heat, add the meat and saute for about 5 minutes. Remove meat with slotted spoon and set aside. Add the onions and saute until golden (I throw in the green scallions or mini-onion tops towards the end). Add the garlic, rosemary and pepper flakes, saute 3 minutes more. Add the escarole, stirring two minutes more. Add the beans, tomato, broth, and salt to taste; bring to a boil. Lower the heat to maintain a gentle simmer, cover, and cook for 10 to 15 minutes. Stir in the reserved meat and season with salt and pepper to taste.
Cook's note: Swiss chard is a welcome substitute for the escarole.
