Escarole brings a bitterness that complements this rich stew. But we do want to keep it in balance and not let the bitterness take over the dish. Salt and acid are the perfect balance to a bitter green. So tasting and adjusting the seasoning in your stew before serving ensures you have the best flavor. Topping your finished dish with a drizzle of olive oil, a squeeze of lemon and a shaving of parmesan makes it even better!
