A Kaiser roll, sometimes referred to as a Vienna roll or even a semmel, is a round hard roll. Originating in Austria, this roll is common in bakeries all over America now. Its crusty exterior and delicate yet dense interior makes it the perfect sturdy choice for juicy sandwiches. Here are four flavorful sandwiches that are perfect on a Kaiser roll.

Pulled Pork

A pork shoulder roast or a Boston butt roast can be a tough cut of meat. But cooked low and slow, which means cooking at 300 degrees Fahrenheit for about 7 hours in the oven, will reap a juicy and tender roast. The meat is then "pulled" or shredded with two forks. The meat is so flavorful that salt and pepper is the only seasoning you'll need. But you can also add a barbecue sauce if you like. Serve on a toasted, buttered Kaiser roll with a slice of raw onion and pickles.

Eggplant Parmigiana

You don't have to be a vegetarian to enjoy this meaty, messy masterpiece. Soak tender ½-inch slices of eggplant in salted water for an hour. While they are soaking, sauté onions, peppers, and mushrooms in a bit of olive oil, and warm up some thick and tangy marinara sauce.

Dip the eggplant slices into an egg wash followed by bread crumbs, and brown in a skillet over medium heat. Spread garlic butter on the inside of the Kaiser rolls and quickly brown under the broiler. Place eggplant cutlet on the roll, top with a slice of mozzarella, top with a spoonful of sautéed vegetables, and cover in marinara. If you're not a fan of eggplant, you can use chicken breast or veal cutlets instead.

French Dip

Containers of thinly-sliced beef in broth are available in many grocery store freezer sections, but you can easily make your own by simmering thin slices of Italian beef from the deli in beef broth. You can top with giardiniera, pickled vegetables, or sautéed peppers, onions, and mushrooms, adding mozzarella or provolone if you like. Some people like horseradish mayonnaise on it. Dip your crusty Kaiser hard roll piled high with meat into a small bowl of the beef broth served on the side.

Breakfast Sandwich

Bagels and English muffins are fine, but a Kaiser roll is better able to soak up all the eggy goodness from two sunny-side up eggs sandwiched between bacon or sausage. Add cheese, or better yet, whip up a quick Hollandaise sauce for even more juicy flavor.
