Steps

Step 1

Make the mustard sauce – In a small bowl, mix together whole grain mustard, mayo, honey, and horseradish. Set aside.

Step 2

Sauté the cabbage – In a skillet over medium heat, melt the butter. Add the onion and cabbage, cooking until soft and slightly caramelized (about 8-10 minutes). Stir in apple cider vinegar and cook for 1 more minute. Remove from heat.

Step 3

Toast the buns – Preheat the oven to 350°F (175°C). Slice the slider buns in half and place them on a baking sheet. Lightly toast for 3-4 minutes.

Step 4

Assemble the sliders – Spread a little mustard sauce on the bottom half of each bun. Layer with warm corned beef, Swiss cheese, and sautéed cabbage. Add the top bun.

Step 5

Brush with butter topping – In a small bowl, mix melted butter, garlic powder, and dried parsley. Brush over the tops of the buns.

Step 6

Bake to perfection – Place the sliders in the oven for 5 minutes, or until the cheese is melty.

Step 7

Serve and enjoy! These are best eaten warm, with extra mustard sauce on the side for dipping.

• Go Spicy: Add a few dashes of hot sauce to the mustard sauce for a kick.

• Make It Low-Carb: Serve everything on lettuce wraps instead of buns!
