The key to cooking without meat is replacing the bold flavors and meaty textures that traditionally accompany beef, chicken and pork with ingredients that are equally satisfying. Eggs, tofu and beans are a few go-to picks, as they pack a hearty punch and can easily be worked into nearly any dish.

An updated version of a Mexican classic, Food Network Magazine's Spaghetti Squash Tostadas recipe showcases a few hearty picks, including protein-rich black beans, plus tender spaghetti squash and roasted cherry tomatoes instead of meat, but it maintains a traditional taste thanks to smoky chipotle power. The beauty of tostadas is that they can be customized to everyone's tastes; after frying the tortillas, mashing the beans and cooking the vegetables, try setting up a DIY toppings bar and let everyone build the preferred dish. For a cool topping, finish each tostada with tangy sour cream, and add a bit of fresh cilantro and lime juice for bright flavor.
