These French Dip Sliders make a fun family meal or an awesome appetizer for your next party. Hawaiian Rolls, hearty roast beef, cheese and caramelized onions. Oh my... what else can I say? You NEED to try these immediately.
While we did not put mustard on our version. Using a good quality, stone ground mustard would work great with these sandwiches. It would give them an extra boost of flavor and texture. You can also add some flair to the garnish if you'd like. Topping of with parsley or sesame seeds would look great and give these a great presentation, especially if you are serving them to a crowd as an appetizer.
