In a large mixing bowl, add the fresh ground beef, breadcrumbs, egg, cumin, ground pepper, and salt. Mix until just combined.

Divide the beef mixture into four equal portions, roll into balls, and flatten into patties about ½ inch thick using wax paper.

Chill patties in the refrigerator for 20-30 minutes for best results.

Preheat grill or skillet over medium-high heat and cook patties for 12-15 minutes, flipping occasionally.

Add cheddar cheese during the last minutes of cooking if desired.

Let patties rest for a minute, then serve on toasted buns with your choice of toppings.
