Whether you're dialing down refined carbs, giving up gluten or watching your sodium intake (bread adds up on that front), these loaf-free sandwiches -- most of which sub in vegetables in place of the usual buns, baguettes, wraps and rolls -- all have one thing in common: They'll satisfy any sandwich craving.

Bun-less BLT? You heard that right -- almost. Instead of playing its usual supporting role, iceberg lettuce steps up its game by sandwiching together this otherwise classic combo of crisp bacon, sliced tomatoes and zesty mayo.

Sandwiched between two hollowed-out English-cucumber halves, this protein-packed lunch delivers a whole lot of crunch.

Hold the hoagie roll, but pack the heat in this classic Italian sub piled high with the usual suspects, including ham, salami, provolone and pepperoncini. This sandwich may be light on carbs, but it's more than meaty, thanks to broiled portobello mushroom caps standing in for bread.

Switch up your next ham and cheese sandwich with a crunchy twist. Sliced sweet jicama will hold everything together.

Why fill up on a flour tortilla when you can wrap up your next burrito with quick-steamed collard greens? This naturally healthified stand-in makes for an instant veggie wrap while giving you a dose of antioxidant-rich vitamin K.

Step aside sub sandwich. Sausage and peppers are moving into the bread-free zone with this trimmed-down version. Translation: You won't miss a thing, except for maybe some unwanted calories.

This inside-out spin on curried chicken salad shifts characteristically crisp apples from the salad to a sandwich bread stand-in.

Slathered with tangy mango chutney and topped with crunchy coleslaw, fiber-rich grilled sweet potato rounds add a nutritional punch to these already lean turkey burgers.
