How decadent does this look?! Take Thanksgiving leftovers (or make them fresh just for this sandwich, because you can) and stack em high atop a sweet potato pancake. Top with another, and you got yourself something to be thankful for. Recipe here.
This is basically a homemade version of your In-N-Out protein-style burger. It sacrifices none of the flavor and I would argue the lettuce adds a refreshing, crisp quality that only adds to the overall burger experience. Get the recipe here.
This is the most literal grilled cheese sandwich out there. You actually grill the cheese and use it instead of bread. Halloumi is a firm cheese that doesn't get all goopy and melty when you heat it, so it makes a perfect base for this sandwich, which happens to be filled with crispy bacon and apple slices. Recipe here.
Thinly sliced zucchini, provolone cheese, and ham make these Italian zucchini sandwiches pretty much everything you ever could have wanted. This recipe calls for breadcrumbs, but if you're gluten-free or want to skip the carbs, go with almond meal or another equivalent! Recipe here.
Cabbage leaves are a little thicker and heartier than lettuce leaves, so they're absolutely perfect for handling all the ingredients that go into a breakfast burrito. This one has spiralized sweet potato noodles which is maybe the best idea I've ever heard. Recipe here.
Putting a philly cheesesteak in a green bell pepper is genius. Genius, I tell you! The flavors are all there, not to mention a bell pepper is like a little precious meat bowl that can hold more than any roll ever could. Recipe here.
Cucumbers, much like lettuce wraps, are a great, refreshing alternative for bread when you're making a sandwich. You can top it with anything, cut it lengthwise and have extra long, thin sandwiches, or widthwise for tiny, adorable round sandwiches. The possibilities are endless.
