Filling soups needn't be heavy on the meat. This hearty meal uses two types of canned beans, chickpeas and red kidney beans, and comes together in just 25 minutes. It's an excellent option for a busy weeknight meal.
Heat a medium saucepan over medium heat; swirl in oil. Add garlic and red-pepper flakes and cook, stirring, 1 minute. Add escarole, toss to coat, and season with salt. Cook until escarole is just wilted, about 2 minutes.
Add kidney beans, chickpeas, broth, and 2 cups water and bring to a simmer. Cook until heated through, about 3 minutes. Season with salt; remove garlic. Top with toasted bread and red-pepper flakes. Serve immediately, with lemon wedges.
