Hosting a party this summer? Of course you are! If you’re looking for an easy-to-make crowd-pleasing main dish, I have just the thing. These next-level awesome, cheesy baked sandwiches have become my go-to, and for good reason. They’re addictively delicious, filling and oh-so easy to make. Here’s how it’s done. 

First, start with some prepared dinner rolls. Slice them up and line your pan. (Tip: Save yourself a headache and line the pan beforehand with foil.)

Then, load those pillow-y soft buns up with ham. I used thin-sliced deli ham and put about three good slices of ham per sandwich. Nothing is worse than a sandwich with no meat, am I right? If ham doesn’t float your boat, turkey, roast beef or any other kind of cold-cut would make a great substitution. You can use whatever meat you feel like…or mix it up! There are no rules here, only deliciousness.

Then lay on the cheese…sliced Swiss cheese to be exact. It is OK if it overlaps a little bit from sandwich to sandwich. It’ll all get melt-y and soft in the oven.

Then plop the tops on each roll.

Meanwhile, at the stove, it’s time to make the super-simple, magical topping. Like most magic things, it starts with some butter. Then add your diced onion, Worcestershire sauce and dry mustard. Cook down ‘til the onions are soft.

Then, spoon that goodness over the sandwiches. Just pour it right on, making sure you hit all the sandwich tops.

Bake at 350° for 15-20 minutes, and then serve them up immediately. You will be amazed at how fast they disappear. Good thing whipping up a second pan will take you only minutes, right?
