Flavor packed and easy-to-make in 30 minutes, Beef and Cheddar Sliders are hard to beat! Cheesy and buttery, with a hint of smokiness from the BBQ Sauce, these delicious sliders can double as an appetizer or a main course depending on the occasion, and are absolutely irresistible!
Preheat Oven to 350°. Slice Hawaiian dinner rolls horizontally and place the bottom half on a 9 x 11" baking sheet. In a small bowl whisk together BBQ sauce, mayo, and 1 teaspoon of Dijon mustard. Spread this mixture equally over the bottom half of Hawaiian rolls.
Layer thinly sliced roast beef and cheddar cheese over the BBQ mixture on the dinner rolls. Place the top half of the dinner rolls over the roast beef and cheese.
Make the sauce by adding butter, brown sugar, remaining Dijon mustard, Worcestershire sauce, and poppy seeds to a small sauce pan. Bring mixture to a boil over a medium heat, stirring occasionally. Remove sauce from heat, and spoon mixture over the sliders.
Cover with foil and bake for 15 minutes. Remove foil and continue to bake for another 5-8 minutes until tops of dinner rolls are golden brown. Remove from oven and let cool for 5 minutes. Cut rolls into individual sliders and then serve warm.
