Vegetarian eating during the holidays can be tricky, as so many classic main dishes are meaty picks, like turkey, ham and beef. If you're hosting the celebration this year, you can plan ahead and make a selection of meatless favorites (in addition to beefier items, if you'd like). But if you'll be gathering at someone else's house and can't guarantee what the host will be serving, it's a good idea to bring at least one vegetarian dish to pass; this way you'll know you have at least one dish to eat come dinnertime.

Bobby's Cauliflower-Goat Cheese Gratin (pictured above) is a go-to pick, as it's every bit as rich and satisfying as a traditional main dish, but it's wholly meat-free. The beauty of this casserole is that it's relatively hands-off to prepare. After arranging cauliflower florets alongside a trio of creamy, nutty cheeses and decadent heavy cream, he simply bakes the dish until the vegetables are soft. Your vegetarian guests will enjoy having a comforting, filling dish available, while meat eaters will appreciate the creamy cheese sauce coating each floret.

For something a bit lighter but still packed with flavor, look to Bobby's Roasted Brussels Sprouts with Pomegranate and Hazelnuts (pictured right) from Food Network Magazine. He starts by roasting sliced Brussels until they're tender on the inside with golden-brown leaves on the outside, then tosses them with a sweet, refreshing mixture of pomegranate molasses and fresh pomegranate seeds, plus crunchy hazelnuts and fresh citrus zest.
