These warm Ham and Gouda Party Sandwiches are a great way to use up leftover ham. Turn dinner rolls into buns and slather them with a roasted garlic dijon mayo and stack with leftover ham and shredded gouda cheese. Brush with butter, sprinkle with everything seasoning and bake until toasted and melty. These are great for feeding a crowd.
Break up a small head of garlic into individual cloves [with the outer skin intact] and place them on to a sheet of aluminum foil. Drizzle with a little olive oil, then fold up the sides of the foil like a purse, and place onto to the middle rack of your preheated 400° oven and roast for 20-25 minutes. Remove and let cool until safe enough to peel off the outer skin of each clove.
MAKE THE SANDWICHES:
In your mini food processor, combine the mayonnaise, roasted garlic, and both mustards until smooth. Scrape down the sides and blending until the ingredients are incorporated.
Preheat your oven to 350°.
Slice the dinner rolls in half horizontally keeping the base and tops intact in one large piece. Place the bottom half of the rolls onto a rimmed metal sheet pan and generously spread the roasted garlic dijon mayo on top. Then layer with ham and shredded gouda. Replace the top of the rolls, brush the tops with melted butter and sprinkle with everything seasoning.
Bake on the middle rack of your preheated oven for 15 to 20 minutes, rotating the pan halfway through for even browning, until the sandwiches are heated through and the cheese is melted. The tops should be golden brown and toasted.
Cut the rolls into sandwiches and serve immediately.
