Beef sliders are miniature hamburgers that you can serve as appetizers or at parties. Learning how to make beef sliders includes making the patties from scratch, but you can substitute frozen mini hamburger patties for convenience.

One simple recipe for a beef slider has the mini hamburger as a flavored beef patty sandwich with mustard and caramelized onions. However, you can add whatever toppings you like on your regular size hamburgers to your beef sliders. If you're serving them at a party or gathering, you can also allow your guests to personalize their beef sliders by offering them common hamburger toppings such as cheese, pickles, salad and ketchup.http://www2.dothaneagle.com/lifestyles/2011/jan/26/super-bowl-party-sliders-ar-1386786/
