Collard greens are mild, earthy, and delicious when treated well. They have broad leaves with solid, firm veins running through them. They have a strong, vegetal flavor and a remarkably hearty texture. This is probably because collards have a stronger flavor and tougher leaf than many other greens. Collard greens can be braised and added to pasta, substituted for long flat noodles in a lasagna dish or rolled and stuffed with rice and vegetables.
