Combine Ground Beef, onion, jalapeño, cilantro and 1/4 cup cheese in medium bowl, mixing lightly but thoroughly. Lightly shape into four 1/2-inch thick patties.
Heat large nonstick skillet over medium heat until hot. Place patties in skillet; cook 10 to 12 minutes turning occasionally, until instant-read thermometer inserted horizontally into center registers 160°F, turning occasionally. About 3 minutes before burgers are done, top evenly with remaining 1/4 cup cheese.
Cooking Tip: To grill, place patties on grid over medium, ash-covered coals. Grill, covered, 8 to 10 minutes (over medium heat on preheated gas grill, 7 to 9 minutes), until instant-read thermometer inserted horizontally into center registers 160°F, turning occasionally.
Cooking times are for fresh or thoroughly thawed Ground Beef. Color is not a reliable indicator of Ground Beef doneness.
Place burgers in tortillas or buns; season with salt and black pepper, as desired. Top with desired toppings.
