It's easy to make a satisfying sandwich with turkey or tuna. But when it comes to meatless fillings? Let's just say satisfying options can be tricky.

There's the trusty PB&J or grilled cheese with tomato, of course. These old standbys are fine in a pinch, but they're not all that exciting (or, it can be argued, all that healthy). What's worse, since they lack produce and protein, they probably won't be able to carry you through to your next meal.

These meat-free and seriously mouthwatering sandwiches, however, are a totally different story. Not only are they made with loads of veggies, they're also made with ingredients like beans, nuts, seeds, tempeh and egg whites, so they're packed with protein—and there's not a boring one in the bunch. Happy eating, guys!
