Preheat the oven to 350 degrees F. Line a 13x9 inch oven safe dish with parchment paper.
Slice the whole slab of Hawaiian buns in half creating a top and a bottom half.
Place the bottom half into the prepared dish and add the sauerkraut spreading it out evenly across the buns.
Spread the Dijon over the sauerkraut.
Lay each slice of the corned beef onto the buns followed by the swiss cheese.
Place the top half of the slider buns on top of the cheese.
Make the glaze by melting the butter and whisking in the Dijon, honey and garlic powder.
Using a pastry brush, glaze the top of the slider buns with half of the melted butter mixture and then sprinkle the everything seed on top.
Place in the oven and bake uncovered for 20 minutes. Once the buns come out of the oven, brush again with the remaining melted butter glaze.
Lift the sliders out of the pan using the parchment paper and slice into individual sliders. Serve at once.
