Preheat oven to 375°F. Slice onions (leave a few on the side). In a medium pan brown onions in 2 tbsp butter, brown sugar, and 1/4 cup of beef broth. Stir occasionally. About 10 minutes until brown and tender.
On a baking sheet, place dinner rolls in the center (DO NOT SEPARATE). Cut down the middle so you have a top half and a bottom half. Layer onions, roast beef, Swiss cheese and LAY’S® Classic Potato Chips on the bottom half. Add the top half of the rolls then place the remaining chips around sliders.
Melt 4 tbsp of butter with thyme, then brush over the top of the rolls. Drizzle the remaining butter and herb over the chips on the baking sheet. Bake for about 15-20 minutes until rolls are golden brown.
