For a different flavor, you can add a packet of dry onion soup mix to the beef mixture or try using Swiss cheese instead of cheddar. If you have picky eaters, you could serve the beef mixture on the side and let them build their own sliders.
For a bit of a kick, add some diced pickles or jalapenos into the beef mixture. Lastly, you can swap out the ground beef for ground turkey or chicken for a lighter version of this delicious dish.
