In a large skillet, cook the bacon over medium heat until crisp; transfer to a plate to drain. In a small bowl, stir together the dressing, pickles, onion and jalapenos. Crumble in the bacon.
Preheat a grill or grill pan to medium-high heat. Form the ground beef into 4 patties and season with salt. Add the patties to the grill and cook, turning once, for about 10 minutes for medium-rare. During the last few minutes of cooking, top the burgers with 2 slices of cheese each.
Divide the burgers among the roll bottoms and spoon the dressing on top. Pile high with the lettuce and fries and cover with the roll tops.
