White Bean Stew with Greens and Tomatoes

Fill a large pot halfway up with water. Bring to a boil and then toss in the greens. Reduce heat to a simmer and cook for 8 minutes. Drain in a colander.
Wipe out any excess water in the pot. Then pour in the olive oil and turn the heat to medium. Add the garlic and crushed red pepper and cook for 1 minute, stirring occasionally.
Add the tomatoes, turn the heat to medium-high, and when the mixture comes to a boil add the beans. Cook for 3 minutes, stirring often.
Reduce heat to a simmer and add the greens. Cook for 5 minutes. Season with salt and pepper to taste. Add some grated Parmesan to finish.
