This Jalapeño Burger recipe spices up your burger with jalapeños in the burgers and on top. Diced jalapeños bring on the heat and Worcestershire sauce gives it a subtle savory flavor. Melted Pepper Jack cheese takes the heat up a notch. Then bacon, pickled jalapeños, crispy fried onions and BBQ sauce take the burger over the top with great flavor.We made this recipe on the Performance Series™ 4-Burner Gas Grill, but you can make it on your grill.
