Mix the ground beef, salsa, and brown sugar together, then form into ¼ lb. patties. (The amount of salsa and sugar can be adjusted as needed to achieve the right consistency. Just make sure the patties aren’t too loose or they’ll fall apart.)
Grill your patties on a Blackstone griddle until they reach your preferred doneness.
Right before you remove the patties from the grill, add the cheese and allow it to melt.
Chop your veggies.
Grab a bun, and build each burger to your liking with your favorite toppings. Bon appétit!
